### sense in the lessons

In science and maths, mass is measured with scales or a balance: 1 kilogram = 1000 grams. Mass stays the same everywhere, but weight (the pull of gravity) changes: on the Moon you weigh less but your mass is the same. In geography, a land mass is a large area of land. Phrases: mass of, masses of, land mass, the masses (ordinary people), go to Mass, mass production.

### note

In maths, mass units: grams (g), kilograms (kg), tonnes (t); 1 kg = 1000 g; 1 tonne = 1000 kg. Everyday people say "weight" when they mean mass; in science they differ (weight is a force, in newtons). Capital M for the church service.
