Because mass is measured in grams, milligrams, kilograms, etc. and grams is the sensible choice considering kilograms would be a ridiculously tiny number.
Also, grams is the "base" measurement, like a unit of 1. Milligrams would look more like a normal number, but grams compares it to something that weighs, well, one gram, which is a lot more known to us. (ie we can lift an object and say it's about a gram, but it's a lot harder to tell if something is one milligram because you would barely even realize you're lifting something.)

The mass of a ruler would be measured in grams (g).
Grams are one unit in which weight can be measured.
Grams
No, a Joule is a unit of energy. Mass is measured in kilograms (or grams)
Mass is a measure of the amount of matter in an object. It is typically measured in units such as kilograms (kg) or grams (g).
A unit of mass is measured in kilograms (kg) or grams (g).
Mass is measured in (I think) grams or kilograms
Mass is a measure of the amount of matter in an object. It is typically measured in units such as grams or kilograms using a scale.
