Hello Lion Solidaire!

To convert units of mass, you have to multiply a value by 10 each time one converts to a smaller unit.

For example, 1 cg = 10 mg, because centigrams (cg) are 1 unit bigger than the milligrams (mg).

This method also requires that one must divide a unit by 10 every time one converts to a bigger unit.

For example, 1 dg = 0.1 g, because decigrams (g) are 1 unit smaller than grams (g).

If you want to go from grams to kilograms, we have to make three leaps to larger units; it will therefore be necessary to divide three times by 10.

For example, 3 g = 0.003 kg.

Hope this enlightens your understanding! Don't hesitate to ask other questions 😉
