5.05 Adjectival expressions and juxtaposed numbers
8 of 15 records
Normally, for numbers used in adjectival expressions, follow the rule given in 5.01 Introduction, i.e. write out those from one to nine and use numerals for the rest:
- seven-hour day
- two-metre-wide entrance
- a 10-year-old boy
If the unit is represented by an abbreviation or symbol, use numerals (see 1.23 The International System of Units (SI)):
- a 2.36 m high jump
- three 5-L containers
or
- three 5 L containers
Do not use a hyphen between a numeral and a non-letter symbol:
- a 90° angle
- four 100 °C thermometers
When a number immediately precedes a compound modifier containing another number, spell out the first or the smaller number:
- ten 34-cent stamps
- 15 one-litre jugs
- two 10-room houses
- 120 eight-page reports
