... How is heat measured? • Heat is measured in two ways. • Heat is measured in calories (c). • One calorie is equal to the amount of energy needed to raise the temperature of 1 g of water by 1 °C. • Heat is also measured in joules (J) because heat is a measurement of energy. • One calorie is equal to ...
