Question

Are the symbols of all units written as singular/plural?

Answer 1

I have multiple doubts related to the usage of singular or plural SI base units when written in both symbol as well as name.

I have framed this question under two parts, namely, Part (a) and Part (b). Each part has three sentences which I have written on the basis of my understanding.

Please answer these 6 sentences/questions.

Part (a):

This page says that while using prefix for e.g., centi as in centimeter, it is

l = 75 cm long.(correct) l = 75 cms long. (wrong) Does this rule is used for all SI prefixes (having powers of 10)?In this regard, we should be saying, or writing that, "how many cm are there in one metre?" (while saying we should say centimter or centimetres?)

Please strike-through the wrong SI unit in the following sentences.

My weight is 70 kg / kgs,

or My weight is 70 kilogram / kilograms.

Part (b):

and the page next to above web link says, we should write:

2.6 m/s, or 2.6 metres per second.

In this regard, we should say, or write:

Its speed is 0.26 metres per second.This pipe is 0.75 metres long.How many cm are there in 2 metres?
