MEASUREMENT OF MASS OR WEIGHT

Measurement of Mass/Weight -

Conversion of Units of Mass/Weight -

The standard unit for measuring mass is gram (g). Kilogram (kg) is the commonly used unit for measuring weights of heavy objects such as weight of a boy, table, etc.

1 kg = 1000 g

Milligram (mg) is the commonly used unit for measuring weights of very light objects such as an alpin, ornaments, etc.

1 g = 1000 mg

Kilogram (kg), hectogram (hg), and decagram (dag) are the units of weight bigger than gram (g).

1 kg = 1000 g

1 hg = 100 g

1 dag = 10 g

Decigram (dg), centigram (cg) and milligram (mg) are the units of weight smaller than gram.

1 g = 10 dg

1 g = 100 cg

1 g = 1000 mg

To convert a lower unit into a higher unit [like decigram (dg) to gram (g), centigram (cg) to gram (g), etc.], we have to divide by 10 or 100 or 1000 etc. and to convert a higher unit into a lower unit [like kilogram (kg) to gram (g), hectogram (hg), to gram (g), etc.], we have to multiply by 10 or 100 or 1000 etc. We also know that division by 10, 100 ,1000, etc. is done

by shifting the decimal point to the left of the given number and multiplication by 10, 100, 1000, etc. is done by shifting the decimal point to the right of the given number.

Conversion of units of Mass/Weight is shown as follows:
