500
Explain how to change a measurement from one unit to another.
To change a longer unit to a shorter unit, multiply by
10, 100, or 1000. Example: To change 5 m to centimetres,
multiply: 5 ? 100 = 500; 5 m = 500 cm
To change a shorter unit to a longer unit, divide by 10, 100, or 1000. Example: To change 50 cm to decimetres, divide: 50 รท 10 = 5; 50 cm = 5 dm
