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 $$6.500 \ \mbox{m}^2$$.
