Grams are a unit of weight. You weigh the fuel container before and after using to find out the weight of fuel concerned. This eliminates temperature variations in fuel volume.

Using grams instead of ounces (by weight) is more accurate since 0.1 ounce is 2.8 grams. It also avoids the confusion between (liquid) ounces as a volume measurement and ounces as a weight measurement (the two are the same only for water, not for any other liquid).

For canister fuel, the same method, weighing before and after use, is used to measure fuel consumption.
