Mass
Triple Beam Balance
Mass: is a measure of the amount of matter in an object
Metric standard for mass is the kilogram (kg) 1kg = 1000 g 1g = 1000 mg
Conversions using mass: 5 kg = g 3200 mg = hg
Weight: a measure of the attraction between two objects due to gravity
the amount of force the Earth’s gravity exerts on an object
Metric standard for weight is the newton (N)
Temperature Temperature In the Metric system temp is measured on the Celsius scale
water freezes at 0 C and boils at 100 C
