Use a calculator to verify your math when converting kilometers to feet. You can also do the conversion manually by performing the math using a pen and paper.
One kilometer is equal to 3,280.83989501312 feet. For simplicity's sake, that number is usually rounded up to 3,281 feet.
Multiply the number of kilometers by 3,281 to convert the measurement to feet. For example, 10 kilometers multiplied by 3,281 equals 32,810 feet.
Write 3281, the number of feet in a kilometer, on one line and then the number of kilometers underneath it. For example, if your measurement is 5 kilometers, multiply each number in the multiplier by 5, making sure to carry over when applicable. The equation in this example is 3281 x 5, which equals 16,405.
