The measurement unit calculator allows online conversions volume, surface (area), length.

convert online

The calculator is a converter of measurement units, it allows to make online quickly and easily **length conversions**,
**area conversions** and **volume conversions**.

The **length conversion calculator** provides the ability to make **length conversions online** easily using a simple syntax.

It is possible to use the **length conversion calculator** to convert 1000m in km, for this, enter :
convert(`1000;m;km`) returns 1.

The **area conversion calculator** allows you to make area conversions online quickly and easily.

It is possible to use the **surface conversion calculator** to convert `1km^2` in `m^2`, enter :
convert(`1;km^2;m^2`) returns 1000000.

The **volume conversion calculator** allows to do volume conversions online quickly and easily.

It is possible to use the **volume conversion calculator** to convert `1km^2` in `m^2`, enter :
convert(`1;m^3;l`) returns 1000.

To practice the different techniques of length and area conversions, several games on measurement conversion are proposed.

convert(number;source_unit;target_unit)

- To convert 1000m in km, you must enter the following formula :

convert(`1000;m;km`) returns 1 - To convert `1km^2` en `m^2`,you must enter the following formula:

convert(`1;km^2;m^2`) returns 1000000 - To convert `1m^3` en `l`, you must enter the following formula:

convert(`1;m^3;l`) returns 1000
