A quantity that has magnitude, or size, but not direction. Mass is a scalar quantity, measured in grams and kilograms. It has magnitude only, and does not depend on direction. So, a dog with a mass of 25 kilograms has the same mass no matter what direction it's travelling in! Time, speed and temperature are all scalars.
