## Conversion formula

The conversion factor from meters to millimeters is 1000, which means that 1 meter is equal to 1000 millimeters:

1 m = 1000 mm

To convert 12 meters into millimeters we have to multiply 12 by the conversion factor in order to get the length amount from meters to millimeters. We can also form a simple proportion to calculate the result:

1 m → 1000 mm

12 m → L(mm)

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

L(mm) = 12 m × 1000 mm

L(mm) = 12000 mm

The final result is:

12 m → 12000 mm

We conclude that 12 meters is equivalent to 12000 millimeters:

12 meters = 12000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 8.3333333333333E-5 × 12 meters.

Another way is saying that 12 meters is equal to 1 ÷ 8.3333333333333E-5 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twelve meters is approximately twelve thousand millimeters:

12 m ≅ 12000 mm

An alternative is also that one millimeter is approximately zero times twelve meters.
