Rules for writing metric terms:• Square the actual unit, not the measurement.
• Use a 0 in front of the decimal point
• Use a space between number and unit symbol
• Don’t use plurals
• No Fractions always decimals
• When moving up go to the left and when moving down go to the right .
• No periods at the end of a measurement

Metric System
• Standard measurement system used in almost all countries and in science
• Easy to convert measurements
• Based on powers of ten
• Convert by moving the decimal point (NO FRACTIONS!)
