How to Convert Grams

To convert grams to another unit of weight, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for grams in the conversion table below.

Then, multiply the weight measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

grams × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
