How do you calculate how many feet are in something?

Calculating how many feet are in something requires two steps: measuring the object and then converting the measurement into feet. The measurement can be made from any metric or English measurement of length, but the conversion requires knowing the ratio of the particular unit of measurement used to one foot.

1. Measure the object

   Use a ruler or tape measure to measure the size of the object in your available unit of measurement. Examples of units of measurement include the inch, centimeter or mile. Write down the measurement.

2. Obtain the conversion information

   Find the conversion factor between your unit of measurement and a foot. One inch, for example, is equal to 0.0833333333 feet.

3. Convert the measurement

   Use your research to convert the measured length into feet. Multiply the measured length by the conversion factor between your unit of measurement and a foot. For example, 3,600 inches X 0.0833333333 feet = 299.99 feet.
