There are 4 main reasons why the metric system is used around the world. No fractions Easy conversions – NO MATH! Based on factors of 10 The same prefixes for units

Length meter (m) Mass gram (g) Volume liter (L) Temperature degrees Celsius (˚C)

Length ruler, meter stick, etc. Mass triple-beam balance, electronic balance Volume ruler, meter stick, graduated cylinder* Temperature thermometer, temperature probe
