Standard units of measurement include the meter for distance, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for light intensity. These standard units are regulated by the International Bureau of Weights and Measures. Common conversions between units of length include that 1 centimeter is equal to 10 millimeters, 1 decimeter is equal to 10 centimeters, and 1 meter is equal to 1000 millimeters or 100 centimeters. When measuring length or distance, it is important to use the correct measuring instrument, start at zero, and report the measurement with the appropriate unit.

5. When measuring remember the following
1. Check the unit of measurement that is needed
2. Decide on the measuring instrument to get a
correct reading with its unit.
3. It is important to use the instrument properly by
always beginning to measure at zero.The end of a
ruler is not the starting point in getting a
measurement.
4. Get the reading and use the correct unit.
