How to perform key conversions involving length measurements
The formulas for conversion are represented below:
Kilometers to Millimeters Formula
m = km x 1000000
Example: 30 kilometers in meters:
mm = km x 1000000
mm = 30 x 1000000
mm = 30000000
Millimeters to Kilometers Formula
km = mm / 1000000
Example: 1500 meters in kilometers:
km = mm / 1000000
km = 1500 / 1000000
km = 0.0015
Frequently asked questions involving length and distance
3 km in millimeters
Considering that 1 kilometer equals 1000000 millimeters, you can use a rule of three to get that 3 km equals 3000000 millimeters.
1 km - 1000000 mm
3 km - x
Apply the rule of three and get:
x km = 3000000 mkm2
x = 3000000 mm
10000 millimeters is equal to how many kilometers?
If every 1000000 millimeters we have 1 kilometer, just divide the number of millimeters (10000) by 1000000, so you will get that 10000 mm equals 0.01 km. Observe the calculation below:
km = mm / 1000000
Km = 10000 / 1000000
km = 0,01
