Use of Decimal in Measuring the Mass

We will learn the use of decimal in measuring the mass.

As we already know that,

1000 grams = 1 kilogram or 1000 g = 1 kg

So, 1 g is one thousandths of a kg.

or, 1 g = \(\frac{1}{1000}\) kg  = 0.001 kg

Similarly, 12 g = 0.012 kg       (12 grams is twelve thousandths of a kilogram)

315 g = 0.315 kg      (315 grams is three hundred fifteen thousandths of a kilogram)

Kilograms and grams can be expressed together as decimals.

For example,

45 kg 200 g = 45.200 kg or 45.2 kg

18 kg 56 g = 18.056 kg

69 kg 41 g = 69.041 kg

101 kg 80 g = 101.080 kg or 101.08 kg

9 kg 315 g = 9.315 kg

111 kg 5 g = 111.005 kg
