## Conversion formula

The conversion factor from kilometers to millimeters is 1000000, which means that 1 kilometer is equal to 1000000 millimeters:

1 km = 1000000 mm

To convert 23.7 kilometers into millimeters we have to multiply 23.7 by the conversion factor in order to get the length amount from kilometers to millimeters. We can also form a simple proportion to calculate the result:

1 km → 1000000 mm

23.7 km → L_{(mm)}

Solve the above proportion to obtain the length *L* in millimeters:

L_{(mm)} = 23.7 km × 1000000 mm

L_{(mm)} = 23700000 mm

The final result is:

23.7 km → 23700000 mm

We conclude that **23.7 kilometers is equivalent to 23700000 millimeters**:
