Usage of decimals in weight — lesson. Mathematics State Board, Class 7.

We can use decimals to measure the weight of the object.

Kilogram\((kg)\), Gram\((g)\) and Milligram\((mg)\) are the measurements used to measure the weight of the object.

\begin{array}{l} 1 g = \frac{1}{1000} kg = 0.001 kg \\ 1 mg = \frac{1}{1000} g = 0.001 g \end{array}

Example:

1. Convert \(65\) \(g\) to \(kg\).

\begin{array}{l} 1 g = \frac{1}{1000} kg \\ 65 g = \frac{65}{1000} kg = 0.065 kg \end{array}

Therefore, \(65\) \(g\) \(=\) \(0.065\) \(kg\).

2. Convert \(705\) \(mg\) to \(g\).

\begin{array}{l} 1 mg = \frac{1}{1000} g \\ 705 mg = \frac{705}{1000} g = 0.705 g \end{array}

Therefore, \(705\) \(mg\) \(=\) \(0.705\) \(g\).
