Numerals

• Use numerals for all numbers with the exception of years (see millions and billions)
• Write out or use "s" in abbreviation (3 lbs)
• Never use (s)

• Use “about” or “approx.” for estimates
• Choose “more than” or “over” based on space (even though "more than" is grammatically correct)
• Avoid approximations in money or compliance contexts

There are six defining factors to consider: currency symbol, placement, use of decimal separator, use of group separator and placement, and number of digits after decimal separator.

Frequently used countries and regions may include:

• US - $1.00
• UK - £1.00
• DE - 1,00 €
• FR - 1 €
• China - CN¥1.00
• Japan - ¥1

For more comprehensive guidelines for all countries and regions we support, visit the L10N wiki on currency formatting.

In Cross Border Trade (CBT) scenarios, the ISO code should precede the amount; follow ISO code guidance.

Avoid trailing zeros in marketing/ads content (Get $5.00 off when you purchase $10.00 or more).

• Use a period as the decimal separator
• Max two decimals
• Use a leading 0 for values under 1 ($0.50)

• If emoji are used, their meaning should be universally understood as well as culturally and contextually appropriate
• Use to enhance greetings or highlight positive experiences without detracting from content clarity
• Use emoji as a visual aid; they should complement—not replace—words.
• Reserve emoji for greetings and delightful occasions, not for transactional or instructional copy.
• Never use to replace actual words or phrases, especially in product or UI content ("NO BUENO" for replacing words with emoji).
• Avoid emoji in titles or critical surfaces unless guidance explicitly allows it.
  

• Spell out common fractions
• Use numerals or decimals in specs and measurements
• Don't mix fraction and decimal styles

• Include a space between number and unit: 12 in, 5 km, 200 ml
• Exceptions often made for °C/°F and %: 72°F, 30%
• No plural “s” on abbreviations: 5 km, not 5 kms
• No periods: cm, not cm.
• Don’t invent abbreviations: stick to widely recognized ones

If space allows, spell it out once in labels or help text, and use abbreviations in tight spots (tables, chips, axis labels).

• 12 inches / 12 in / Length (in)
• 5 feet / 5 ft / Height (ft)
• 3 yards / 3 yd / Distance (yd)
• 10 miles / 10 mi / Distance (mi)
  
• 10 millimeters / 10 mm / Thickness (mm)
• 15 centimeters / 15 cm / Height (cm)
• 2 meters / 2 m / Length (m)
• 5 kilometers / 5 km / Distance (km)
  
• 8 ounces / 8 oz / Weight (oz)
• 10 pounds / 10 lb / Weight (lb)
• 250 grams / 250 g / Weight (g)
• 3 kilograms / 3 kg / Weight (kg)

We don't support superscripts, so use:

• 50 sq m / Area (sq ft)

• Write out in a sentence (1.2 million) but shorten everywhere else (1.2M)
• Only one "M" or one "B" - always uppercase and next to the numeral
• Default to two significant digits; don't round up

• Write out or use "s" in abbreviation (3 lbs)
• Never use (s)

• Prefer words for clarity in text (e.g., 10 to 12 kg)
• Use an en dash for date and currency ranges (e.g., Jan 1–4, $50–$60 million)
• Avoid hyphens and ordinals (e.g., Aug 1-4, Oct 3rd)

Rewrite the sentence to avoid starting with a numeral

• Use a comma as a separator for readability (1,200)
• Avoid “K” in a sentence but use in badges, chips, or other tight UI
