How do you align different expressions of measurements?
Use the slash (/) in place of ‘per’ between two abbreviated units of measurement.
- 40 psi/ft
- 15 cm/s
- 40 lbm/ft
Use the degree sign (°) with angles, temperatures [except metric K (Kelvin)], and compass coordinates.
- 20° slope
- 65°
- 2°W
Abbreviate units of measurement in the text only when used with numerical values (unless the abbreviation replaces a very long phrase, such as ‘several scf/D’ for ‘several standard cubic feet per day’). 25 ft
- 50 x 103 ft3/D
- 10 dm3
- 3 cm3
Use the same abbreviation for both singular and plural forms of measurements.
