The Metric System Types of Measurement Mass – the property of body that causes it to have weight in a gravitational field. Volume - the amount of 3 dimensional space occupied by an object. Length – the linear extent in space from one to end to the other. Temperature – the degree of hotness or coldness of a body or environment.

Converting within the Metric System Refer to the chart on the hand out. When moving up the step – divide OR move the decimal to the left When moving down the step – multiply OR move the decimal to the right Convert the following: 560 mm to metres 0.56m 34 000 mL to litres 34 L 78 000 000 mg to kilograms 78kg 5km to centimetres 500 000 cm 50L to millilitres 50 000 mL 0. 000 05kg to milligrams 50 mg
