Question

The symbol for units should be written with a capital letter.
(A) True
(B) False

Answer 1

Hint: Unit is an internationally accepted reference standard to measure a physical quantity. Representation of any physical quantity without units would be meaningless. There are certain rules to be followed while writing units along with their corresponding quantity.

Complete step-by-step solution: We must know whether the symbols for units are named after a scientist or not.
If the units are named after a scientist, the symbols of the units should be written with a capital letter. For example: W for Watt, H for Henry, A for Ampere.
If the units are not named after a scientist, the symbols of those units must be written by small letters. For example: ‘s’ for time, ‘kg’ for mass and ‘m’ for metre.
Additional information: There are other conventions to be followed while writing units.
The symbols of the units should not be written in plural form. For example: It should be written as 5 m and not 50 mts.
Accepted symbols only must be used for representing the symbols of the unit. For instance, the symbol of the unit second must be s and not sec.
There should be no punctuation marks or full stop within or at the end of the symbols. Also a small gap should be left between the number and the symbol of the unit.

Note: We should note that the units named after scientists should not be written with a capital initial letter. For example, we should write the unit of current as 2 ampere and not 2 Ampere.
