## 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 289 decimeters into millimeters we have to multiply 289 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

289 dm → L_{(mm)}

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

L_{(mm)} = 289 dm × 100 mm

L_{(mm)} = 28900 mm

The final result is:

289 dm → 28900 mm

We conclude that **289 decimeters is equivalent to 28900 millimeters**:

289 decimeters = 28900 millimeters
