A number of different units of measurement were used in Chile to measure quantities like length, mass, area, capacity, etc. From 1848, the metric system has been compulsory in Chile.[1][2]

## Pre-metric units

Spanish customary units were used before 1848.[1][3]

### Length

To measure length several units were used. Legally, one vara is equal to 0.836 m.[1] Some of the units and their legal values as follows:[1][4]

• 1 línea = 1432 vara
• 1 pulgada = 136 vara
• 1 pie = 13 vara
• 1 cuadra = 150 vara
• 1 legua = 5400 vara

### Mass

Several units were used to measure mass. One libra is equal to 0.460093 kg. Some other units are given below:[1][4]

• 1 grano = 19216 libra
• 1 adarme = 1256 libra
• 1 sastellano = 1100 libra
• 1 onza = 116 libra
• 1 arroba = 25 libra
• 1 quintal = 100 libra

### Capacity

Mainly two systems, dry and liquid, were used to measure capacity in Chile.

#### Dry

One almud was equal to 8.083 L.[1][4] 12 almud were equal to one fanega.[1][4]

#### Liquid

One cuartillo was equal to 1.111 L.[1] 32 cuartillo were equal to one arroba.[1][4]
