General Rules for Abbreviating Units of Measure
Always abbreviate units when reporting numerical information.
Unless otherwise noted, singular and plural units are abbreviated the same.
Percent is not abbreviated, but is represented by the familiar …show more content…
When do you abbreviate units vs. spelling out the unit(s) as word(s)? abbreviate units when you are reporting a numerical value:
"The maximum depth achieved by the ROV was 124 m approximately 2.3 km due south of Pt. Lobos."
spell out the unit as a word when using it in a non-numerical context, e.g.,
"All measurements were made in millimeters unless otherwise indicated."
When starting a sentence with a number and unit, both must be spelled out as words (this is something to avoid, if possible), e.g.,
"One thousand six hundred and eighty-seven kilograms of ground beef were randomly sampled and tested for E.coli contaminants between 21 August and 21 November, 1995."
