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