What is the gram a unit of? Is it volume, mass, capacity, or density?
We know from our metric conversions that 1000 grams is equal to one kilogram. Kilograms are the standard unit for mass. This means that both grams and kilograms can be used to measure mass. Therefore, the correct one of the four options is mass.
In terms of the other three options, volume, capacity, and density, let’s look at what they can be measured in. We can measure volume in centimeters cubed or meters cubed. Capacity can be measured in milliliters or liters. And finally, density can be measured in grams per centimeter cubed or kilograms per meter cubed. There are other units we can use to measure volume, mass, capacity, and density, but these are the most common.
