Question

write any five rules and conventions of writing sI units

Answer 1

rule1- Lower case is used to write the names of units.Units named after the scientists too are written in lower case,for example,newton,metre,kelvin etc.

rule2- Symbols of units that bear the name of the scientists are written in upper case.
Example:
       kelvin- K
       newton-N
       joule- J
rule3- Other symbols not named after scientists are written in lower case.
       Example- symbol for second- s
                      symbol for metre-  m
                      symbol for kilogram- kg
                      symbol for gram- g
rule4- Symbols of units are never followed by a full stop.
         Example:
                      Symbol for kilogram is kg (not kg.)
                      Symbol for centimetre is cm (not cm.)
          However, when a sentence ends with the symbol of a unit,it is followed             by a fullstop.
rule5-  Units are written in plural only when used in words, but symbols remain             unaltered.
          For example:
                              symbols for 5 metres is 5m (not 5ms)
                              symbols for 3 kilograms is 3 kg (not 3 kgs)
