280in. to dam

Answer 1

0.7112 dam

Explanation:

You want to convert 280 in to units of dam.

Conversion

The conversion factors will multiply by units we want and divide by units we don't want. Each conversion factor will have a value of 1, which is to say it will change the units without changing the measure.

`280\text{ in}=280\text{ in}*\frac{0.00254\text{ dam}}{1\text{ in}}=\boxed{0.7112\text{ dam}}`

Additional comment

The conversions we are more familiar with are 2.54 cm = 1 in, and 10 m = 1 dam (decameter).

1 dam² = 1 are, a unit of area = 100 m². The more familiar unit is 1 hectare, or 100 are, about 2.471 acres. This is all to say that a "dam" is not a unit seen very often.
