## 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 68 decimeters into millimeters we have to multiply 68 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

68 dm → L_{(mm)}

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

L_{(mm)} = 68 dm × 100 mm

L_{(mm)} = 6800 mm

The final result is:

68 dm → 6800 mm

We conclude that **68 decimeters is equivalent to 6800 millimeters**:

68 decimeters = 6800 millimeters
