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 2438 decimeters into millimeters we have to multiply 2438 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

2438 dm → L_(mm)

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

L_(mm) = 2438 dm × 100 mm

L_(mm) = 243800 mm

The final result is:

2438 dm → 243800 mm

We conclude that 2438 decimeters is equivalent to 243800 millimeters:

2438 decimeters = 243800 millimeters
