Numbers and units of measure¶
When using numbers in running text, follow these guidelines:
Spell out numbers from one to nine. However, use numerals for units of measure.
Use Arabic numerals for numbers above ten.
If a numeral starts a sentence, spell it out. For example: Five thousand environments have been deployed during the last six months.
In one sentence, use either a spelled-out number or a numeral, not both.
Use a comma if a numeral includes more than 4 digits. For example: 50,000.
In mathematical expressions:
Use the x symbol for multiplication.
Add a space between numbers and operators. For example: 256 x 2 = 512.
When using units of measure in running text, follow these guidelines:
Use the corresponding unit symbol if a unit of measure comes immediately after a numeral.

Do not pluralize an abbreviated unit of measure.
Add a space between a numeral and a unit of measure.
