## How many feet (ft) are in 1 kilometer (km)? What is the formula for how to convert feet to kilometers (ft to km)?

**1 foot (ft) = 0.0003048 kilometer (km)**

So we can say that there is 0.0003048 kilometer in 1 foot.

This means that the multiplication conversion factor to convert a quantity expressed in a foot unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 0.0003048.

Inversely (or reciprocally),

**1 kilometer (km) = 3,280.8398950131 feet (ft)**

So we can say that there is 3,280.8398950131 feet in 1 kilometer.

This means that the division conversion factor to convert a quantity expressed in a foot unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 3,280.8398950131.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in feet to an equivalent quantity of length expressed in kilometers (ft to km). Both formulas will yield the same result. The formulas are:

km = ft × 0.0003048→ This is the formula based on the multiplication conversion factor.

and

km = ft ÷ 3,280.8398950131→ This is the formula based on the division conversion factor.

For example, if you have a length of 150 feet that you want to convert to kilometers, you would use either of the two formulas as follows:

km = 150 ft × 0.0003048 = 0.04572 km

km = 150 ft ÷ 3,280.8398950131 = 0.04572 km

So, the result is the same using either formula, which is 0.04572 kilometer.
