International System of Units rules
International System of Units rules
(OP)
Just a question about the use of the right
S.I. rules and style conventions in the
English Technical Writing.
Why I always see (and in this forum too):
volts ohms meters
and not
volt ohm meter ?
Thanks,
Renzo Del Fabbro

RE: International System of Units rules
10 volts 25 ohms 239 meters
10 V 25 Ω 239 m
RE: International System of Units rules
Second I see also NIST let the use of plural for
volt ampere and ohm :(

Third 10 V is correct not 10 volts :)

RE: International System of Units rules
ANSI/IEEE Std 945-1984 IEEE Recommended Practice for Preferred Metric Units for Use in Electrical and Electronic Science and Technology
Item SI Symbol (Unit)
6.6 V (volt)
3.4 m (meter)
6.26 Ω (ohm)
The unit can be singular (volt) or plural (volts). E.g. 1 volt, 2 volts, expresion in volts, volt/meter or V/m for Electrical Field Intesity etc. The singular versus plural is to be applied according to the English grammar.
