A spring balance operates by the compression of a spring. It has been calibrated on the Earth in grams.
A beam balance operates by balancing standard masses against the unknown mass to be measured.
The same unknown mass is measured with each balance on the Earth and on the Moon.
The gravitational field strength on the Earth is greater than that on the Moon.
How would the measurements on the Earth compare with those on the Moon?
