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 150 millimeters into decimeters we have to multiply 150 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

150 mm → L_(dm)

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

L_(dm) = 150 mm × 0.01 dm

L_(dm) = 1.5 dm

The final result is:

150 mm → 1.5 dm

We conclude that 150 millimeters is equivalent to 1.5 decimeters:

150 millimeters = 1.5 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.66666666666667 × 150 millimeters.

Another way is saying that 150 millimeters is equal to 1 ÷ 0.66666666666667 decimeters.

Approximate result

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

150 mm ≅ 1.5 dm

An alternative is also that one decimeter is approximately zero point six six seven times one hundred fifty millimeters.
