Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 740 millimeters into decimeters we have to multiply 740 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

740 mm → L_(dm)

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

L_(dm) = 740 mm × 0.01 dm

L_(dm) = 7.4 dm

The final result is:

740 mm → 7.4 dm

We conclude that 740 millimeters is equivalent to 7.4 decimeters:

740 millimeters = 7.4 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.13513513513514 × 740 millimeters.

Another way is saying that 740 millimeters is equal to 1 ÷ 0.13513513513514 decimeters.

Approximate result

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

740 mm ≅ 7.4 dm

An alternative is also that one decimeter is approximately zero point one three five times seven hundred forty millimeters.
