the metric system uses units based on multiples of ten. the basic units of measure in the metric system are the meter, the liter, and the gram. metric prefixes tell what multiple of ten the basic unit is multiplied by. below is a chart of metric prefixes and their values. the ones rarely used are shaded.
prefix kilo (k) hecto (h) deka (da) unit (m, l, g) deci (d) centi (c) milli (m)
meaning 1000 100 10 1 0.1 0.01 0.001
multiply when changing from a greater unit to a smaller one; divide when changing from a smaller unit to a larger one. the chart is set up to help you know how far and which direction to move a decimal point when making conversions from one unit to another.
