## 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 4.2 meters into millimeters we have to multiply 4.2 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

4.2 m → L(mm)

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

L(mm) = 4.2 m × 1000 mm

L(mm) = 4200 mm

The final result is:

4.2 m → 4200 mm

We conclude that 4.2 meters is equivalent to 4200 millimeters:

4.2 meters = 4200 millimeters ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00023809523809524 × 4.2 meters.

Another way is saying that 4.2 meters is equal to 1 ÷ 0.00023809523809524 millimeters.

## Approximate result

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

4.2 m ≅ 4200 mm

An alternative is also that one millimeter is approximately zero times four point two meters.
