## How to Convert Kilometers to Feet

*Example: How many feet are equivalent to 21.69 kilometers?*

As;

1 kilometers = 3280.84 feet

21.69 kilometers = Y feet

Assuming Y is the answer, and by criss-cross principle;

Y equals 21.69 times 3280.84 over 1

(i.e.) Y = 21.69 * 3280.84 / 1 = 71161.4196 feet

Answer is: 71161.4196 feet are equivalent to 21.69 kilometers.
