Answer 1

What is the numerical difference between one tenth and one one-hundred

Answer 2

The 4 fundamental metric units are:

Metre - length.

Kilogram - mass (or weight).

Second - time.

Amp - electric current.

The above units are defines in terms of physical quantities. All other units are derived from these 4. This is why it is sometimes called the 'MKSA system'.

Derived units include:

Are (or Hectare) - area

Litre - volume or capacity

°C (degrees Celsius) - temperature

Volt - electrical voltage

Joule - energy

Watt - power (=Joules per second).

Bar - pressure.

Newton - force

All these units can then have prefixes added to them to make them bigger or smaller, for example micro-, milli-, centi-, Kilo-, Mega-.
