Another system of units is the traditional system, which units are:

## Measurements of length

Name | Equivalence |

Inch | aprox. 2.3 cm |

Span | 9 inches |

Foot | 12 inches |

Pole | 3 feet |

Step | 5 feet |

Mile | 1000 steps |

League | 4 miles |

To convert a unit into another we will use the column of equivalences.

Convert $$5$$ feet into inches. Since:

$$1$$ foot $$=12$$ inches, then:

$$5$$ feet $$=5\cdot12$$ inches $$=60$$ inches.

Namely, $$5$$ feet are $$60$$ inches.

## Measurements of mass

Name | Equivalence |

Ounce | $$\dfrac{1}{4}$$ pound |

Pound | 454 g |

To convert a unit into another we will use the column of equivalences.

Convert $$32$$ ounces into pounds, using:

$$1$$ ounce $$=\dfrac{1}{4}$$ pound, then:

$$32$$ ounces $$=32\cdot\dfrac{1}{4}$$ pounds $$=8$$ pounds.

Therefore, $$32$$ ounces are $$8$$ pounds.

## Measurements of capacity

The unit to measure liquids was the pitcher (which are $$16,3$$ liters), while for the solids was the bushel (which are $$55,5$$ liters).

## Measurements of surface

To measure surface, only a bushel of soil was used, which is approximately $$6.500 \ \mbox{m}^2$$.
