Numbers, Units and Currencies: Facts AI Can Quote Correctly

Short answer: write every figure so that it still makes sense when an AI assistant lifts it out of the page and shows it alone. That means giving the unit, the currency, the scope and the date next to the number, using unambiguous date and decimal formats, writing ranges as ranges, and avoiding vague words such as “about”, “soon” or “affordable” where a real value exists. A number without its context is easy to misquote, and an AI answer that misquotes you is usually repeating something your page left unclear.

People rarely notice how much meaning sits around a number. On your page, the surrounding sentences explain what “50” refers to. In an AI answer, a sentence or two may be pulled from several sources, and the surrounding explanation can disappear. If the figure only makes sense with the previous paragraph, it can come out wrong. This article is a practical guide to writing figures that survive being quoted.

Why numbers go wrong in AI answers

AI assistants summarise, combine and paraphrase. Numbers are fragile in that process for a few reasons.

Context gets cut. A figure from a table cell or a short sentence may be reused without the heading that explained it.
Several sources disagree. If your page says one thing and an old directory listing says another, the answer may pick either, or blend them.
Formats vary. “1,5” can mean one and a half in one country and one thousand five hundred in another. “03/04” can be March or April.
Old figures persist. Without a date, a price from last year looks as current as one from today.

You cannot control how a system reads your page, but you can remove the ambiguity that causes avoidable mistakes. It is the same discipline that good editors apply to reports for human readers.

Always attach the unit and the scope

A number should travel with its unit. “The tool handles 500” is incomplete: 500 what, per what, and under which conditions? Compare the following two versions.

Weak: “Our plan includes 30.”
Better: “The plan includes 30 articles per month for one website.”

The second version contains the quantity, the thing counted, the period and the scope. If someone quotes only that sentence, it is still accurate. Apply this habit across the site:

Quantity and thing: “30 articles”, not “30”.
Period: per month, per year, per user, per order.
Scope: what the figure covers and what it excludes, such as “excluding tax” or “for one site”.
Measurement: metric or imperial, and the conversion if your audience uses both.

In tables, repeat the unit in each column header and avoid cells that contain only a bare number with the explanation somewhere above.

Be explicit about currencies and taxes

The symbol for dollars is shared by several currencies, and the same numeral can mean very different amounts. If your readers are international, a bare symbol is not enough.

Write the code or the name once near the figure: “USD 49” or “49 US dollars”, then the symbol if you like.
State whether prices include tax. “Prices exclude VAT” or “VAT is added at checkout” prevents a common misquote.
Say whether a price is monthly or yearly, and whether a discount applies to the yearly option.
If prices differ by country, say so and link to the page that shows the local price.
Do not mix currencies in one table without a clear label.

If you change prices, update the page and date it. Old figures that remain on other websites are beyond your control, but a clear current page is the best reference you can offer.

Use unambiguous dates and number formats

Date and decimal formats vary between countries, and a system reading your page cannot always tell which convention you meant.

Write the month as a word: “17 October 2026” is clear in every locale. If you use numbers, the ISO form 2026-10-17 is unambiguous.
Include the year in any date that might be quoted later.
Use one decimal convention per page and avoid mixing them. For international audiences, remember that “1,200” and “1.200” can both mean twelve hundred, while “1,5” means one and a half in many countries, so add a short note or use words when the audience is mixed.
Give time zones for times, such as “09:00 UTC” or “09:00 Vilnius time”.
Avoid relative words such as “last month”, “recently” or “next year” in facts that will be quoted. Replace them with the actual period.

These small choices make little difference to a person reading the page in context, and a lot of difference when a sentence is reused elsewhere.

Write ranges, estimates and approximations honestly

Real life is full of approximate figures, and honesty about uncertainty is good practice. The problem is vagueness that offers no information. Compare “a few weeks” with “usually two to four weeks”, or “cheap” with “from 15 euros per month”.

Show ranges with both ends: “two to four weeks”, not “weeks”.
If a figure is an estimate, say what it is based on: “in our own tests”, “from our customer records for 2025”, or “according to the supplier”.
If a figure is a limit, say whether it is a hard limit or a typical value.
Avoid rounding that changes meaning. “Nearly 100” and “over 100” point in different directions.

Do not invent a precise number to look authoritative. A clearly stated range is more trustworthy than a made-up exact figure, and it is also easier to defend if someone checks it.

Show where the figure comes from and when it was checked

Figures with a source and a date are easier to trust, and easier for a system to treat as current. For each important number, add a short note in the text: where it came from, and the month and year it was checked.

Link to the original source when it is public, instead of a secondary article that repeats it.
Add “checked in October 2026” or a similar phrase for facts that change.
Keep a single page as the source of truth for things like pricing, limits and supported countries, and make other pages link to it rather than repeat the numbers.
When you update a figure, search the site for the old one so that no page contradicts the new page.

Contradictions between pages on your own site are one of the most common reasons for confused answers. A quarterly check of your key numbers is a simple way to prevent them.

A before-and-after example

Consider this paragraph from a hypothetical bike repair shop: “We fix most bikes quickly and cheaply. A standard service is 60 and usually takes a couple of days. Open late on some days.” Taken alone, an AI answer could say almost anything about it.

Now the revised version: “A standard bicycle service costs 60 euros including VAT and is usually completed within two working days. Prices were last checked in October 2026. The shop is open until 20:00 on Tuesdays and Thursdays, Vilnius time.” The second version has a currency, a tax statement, a time range, a date and a time zone. Each sentence can be quoted without the others and remain true. The page is also more useful to a customer, which is the real aim.

A quick review routine for key pages

You do not need to audit every article. Start with the pages where wrong numbers do the most damage: pricing, plans, limits, opening hours, delivery times, supported countries and contact details. Set aside an hour each quarter and go through them with a short list of questions.

Does every number have a unit, a period and a scope?
Is each price shown with a currency and a tax statement?
Is every date written in an unambiguous format, with the year?
Does any other page on the site, including old blog posts, show a different figure for the same thing?
Is there a visible “last checked” or “last updated” line on the page that holds the facts?
Do the page title, headings and the FAQ answers agree with the body text?

When you find a contradiction, fix the source page first and then update or remove the repeated mention elsewhere. If an old article quotes a figure that you now change often, replace the figure with a link to the page that holds the current value. This keeps the number in one place and reduces the chance that an outdated copy is picked up.

It is also worth asking an assistant the questions your customers ask, and reading the numbers in the replies. If an answer gets a figure wrong, look at your own pages first for ambiguity before blaming the tool, and check external listings that you control, such as directories and profiles. Changes can take time to be reflected, so repeat the check after a few weeks.

Figures about your own business, such as prices, limits and dates, should come from you, so keep them on one page and review them regularly. See the pricing page for plans.

The bottom line

Make every figure self-contained: a value, a unit, a scope, a date and, for money, a currency and a tax statement. Use unambiguous formats, write ranges honestly, cite sources, and keep one page as the source of truth. These habits protect you from misquotes in AI answers and make your pages clearer for ordinary readers as well.

FAQ

Should I write prices with a symbol or a currency code?

Use the code or the currency name at least once near the price, such as USD 49 or 49 euros, because symbols are shared by several currencies.

Is it better to use exact numbers or ranges?

Use exact numbers when you know them and ranges when you do not. Avoid vague words like “cheap” or “soon” when a real value is available.

How do I stop old prices from appearing in AI answers?

You cannot remove them from other websites, but you can keep a clear, dated pricing page, update it when things change, and correct listings you control.

What date format is safest?

Writing the month as a word, such as 17 October 2026, or using the ISO form 2026-10-17, avoids confusion between day-first and month-first formats.

Do tables help with numbers?

They can, if every column header includes the unit and the table has a clear caption. Avoid bare numbers whose meaning depends on text far above the table.
