What do you use to measure mass

To measure gravitational mass one of the methods includes using a spring balance. a balance is a type of scale that is different because it uses known mass to measure the unknown mass. so technically the method measures the weight.

also if you just want to know normal mass then just weigh the object on the scales because technically speaking when you want to see your weight you are actually seeing your mass. because mass never changes whilst weight is from the result of gravity and always changes, so yeah. I hope thos actually makes some sort of sense
