In science, physical quantities like length, weights etc are measured in units of metric or International System of units.

Some importance units are as follows:

1. Meter (m) for length.

2. Liter (L) for volume.

3. Gram (g) and kilogram (kg) for mass.

4. Degree Celsius (oC) for temperature.

5. Second for (s) time.

Given that the length of an object = 45.2 cm

SI unit of length is m

100 cm = 1.0 m

Therefore

45.2 cm * 1 .0 m/100 cm

= 0.452 m
