Metric System

Metric Conversions Each prefix has a numeric meaning. Each space on the metric scale represents a multiplier of 10. SO: 1 km is 1000 times larger than 1 meter (kilo = 1000 or 10 3 ) 1 cm is 100 times smaller than 1 meter (centi = 1/100 or 10 -2 ) The base of the scale is 10 0 and is referred to as the unit. There are several units that could go here: Grams Meters Liters Bytes Fareds
