## 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 650 decimeters into millimeters we have to multiply 650 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

650 dm → L_{(mm)}

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

L_{(mm)} = 650 dm × 100 mm

L_{(mm)} = 65000 mm

The final result is:

650 dm → 65000 mm

We conclude that **650 decimeters is equivalent to 65000 millimeters**:

650 decimeters = 65000 millimeters

## Alternative conversion
