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,

$705$

$mg$

$=$

$0.705$

$g$ .
