Numbers

• For smaller numbers (less than 1 million) we recommend writing numbers with digits, not words, as they're generally easier to understand
• Exceptions: Consider writing out a number with words if
  • it's part of a proper noun
  • it makes the phrase clearer (if in doubt, check with the Content Design team)
  • it’s an ordinal number
    • For example, 3rd should be written as third
  • it makes the phrase clearer when citing large, round numbers
    • For example, 3 million, 81 million, 2.5 billion, 7 trillion
• For numbers with 4 or more digits, use commas between every group of 3 digits starting from the right (breaking up numbers with commas improves readability)
• Don’t use abbreviations such as 130k or 130K (we can’t assume all audiences understand these abbreviations)
