The reading of mass measurements follows the same procedure applied to linear measurements. Examples:

Read the following measurement: 83,731 hg.

kg | hg | dag | g | dg | cg | mg |

8 | 3, | 7 | 3 | 1 |

Read "83 Hg and 731 Decigrams".

Read the measurement: 0.043g.

kg | hg | dag | g | dg | cg | mg |

0, | 0 | 4 | 3 |

It reads "43 milligrams".

## Important Relationships

We can relate mass measurements to volume and capacity measurements. So for the **pure water** (distilled) at a temperature of **4ºC **The following equivalence is valid:

1kg 1dm^{3} 1L

The relationships also apply:

1m^{3} 1 Kl 1t

1cm^{3} 1ml 1g

*Note:*

For large masses, we can also use the following special units:

1 at sign = 15 kg

1 ton (t) = 1,000 kg

1 megaton = 1,000 t or 1,000,000 kg
