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 801 decimeters into millimeters we have to multiply 801 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

801 dm → L_(mm)

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

L_(mm) = 801 dm × 100 mm

L_(mm) = 80100 mm

The final result is:

801 dm → 80100 mm

We conclude that 801 decimeters is equivalent to 80100 millimeters:

801 decimeters = 80100 millimeters
