Conversion formula

The conversion factor from decimeters to millimeters is 100, which means that 1 decimeter is equal to 100 millimeters:

1 dm = 100 mm

To convert 270 decimeters into millimeters we have to multiply 270 by the conversion factor in order to get the length amount from decimeters to millimeters. We can also form a simple proportion to calculate the result:

1 dm → 100 mm

270 dm → L_(mm)

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

L_(mm) = 270 dm × 100 mm

L_(mm) = 27000 mm

The final result is:

270 dm → 27000 mm

We conclude that 270 decimeters is equivalent to 27000 millimeters:

270 decimeters = 27000 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 3.7037037037037E-5 × 270 decimeters.

Another way is saying that 270 decimeters is equal to 1 ÷ 3.7037037037037E-5 millimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred seventy decimeters is approximately twenty-seven thousand millimeters:

270 dm ≅ 27000 mm

An alternative is also that one millimeter is approximately zero times two hundred seventy decimeters.
