The metric system is easy to learn and simply to use. There are only a few basic units, and they are generally related to each other by simple factors of 10. The metric system has a single unit for weight (grams), volume (litres), and another for length (metres). Smaller and larger units can be modified with a prefix. For example, *kilo* means 1000 times bigger, so a kilogram is 1000 grams and a kilometer is 1000 metres.

**Metric Abbreviations**

Metric Base Unit Abbreviation |
Other Common Metric Abbreviations |

litre, L | millilitre, mL |

gram, g | kilogram, kg |

**Common Metric Equivalents in the Food-Service Industry**

Weight (Mass) |
Volume (Liquid) |

1 gram = 1000 milligrams | 1000 milliliters = 1 litre |

1000 grams = 1 kilogram |

**Conversions between U.S. Standard and Metric Measurements**

Weight Conversion between U.S. Standard Measure and Metric |
Volume Conversion between U.S. Standard Measure and Metric |

1 ounce = 28.35 grams | 1 litre = 33.8 fluid ounces |

1 kilogram = 2.21 pounds |

`Example 1`

Convert 24 fluid ounces of concentrate to litres and then millilitres.

`Solution`

\[24\, fl.oz. \times \frac{1 L}{33.8\, fl.oz.} = 0.7101L\qquad (rounded\, to\, 4\, decimal\, places)\]

\[0.7101L \times \frac{1000mL}{1L} = 710.1mL \qquad (rounded\, to\, 1\, decimal\, place)\]

`Example 2`

Convert 15 pounds to kilograms.

`Solution`

\[15\, lbs \times \frac{1 \,kg}{2.21\, lbs} = 6.7873 kg \qquad (rounded\, to\, 4\, decimal\, places)\]
