What does 5mm represent in km?

Answer 1

You're going to be writing a small length in terms of a really long one. That means the answer is going to be really small. You've chosen to express 5 mm in km, and that's 5 millimeters or 5 thousandths of a meter in terms of kilometers or thousands of meters. To convert millimeters to meters, you'll have to divide by 1,000. And to convert meters to kilometers, you'll have to divide by 1,000. So to convert millimeters to kilometers, you'll have to divide by 1,000,000 (a million), or 106. 5 mm / 106 = 5 x 10-6 kilometers, or 0.000005 kilometers.

Answer 2

5mm = (5 / (1 000 * 1 000)) = 0.000005 km

Answer 3

1 km = 1000m. All you have to do is to divide 5m by 1000: 5m/1000 = 0.005 km

Answer 4

5mm represents 0.005 km. To convert from millimeters to kilometers, you divide by 1,000,000 (since there are 1,000,000 millimeters in a kilometer).

Answer 5

5 mm is 0.000005km
