The SI unit of measurement for length is the metre. Its symbol (not abbreviation) is m.
The unit for mass is the kilogram; its abbreviation is kg.
The sievert is the SI derived unit of ionizing radiation dose. The Sv is its abbreviation.
No, although a centimetre is a unit of length, the meter (m) is the SI base unit for length. 1 cm = 0.01m. Not only isn't it a base unit, it's not even an SI unit! In the SI system, multiples are based on 10 raised to the power of multiples of 3. So, whereas a millimetre, is an SI unit, a centimetre is not -although, of course, it is a metric unit.
The SI unit of mass is the kilogram, abbreviated kg.CommentSI uses symbols, not abbreviations. Therefore, the rules for abbreviations (e.g. the use of full-stops / periods) do not apply.
The SI unit for moment (torque) is a newton metre and its abbreviation is "N.m"

Force is measured in newton. Weight is a force; therefore it is also measured in newton.
