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 743 decimeters into millimeters we have to multiply 743 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

743 dm → L_(mm)

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

L_(mm) = 743 dm × 100 mm

L_(mm) = 74300 mm

The final result is:

743 dm → 74300 mm

We conclude that 743 decimeters is equivalent to 74300 millimeters:

743 decimeters = 74300 millimeters
