Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 829.8 millimeters into decimeters we have to multiply 829.8 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

829.8 mm → L_(dm)

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

L_(dm) = 829.8 mm × 0.01 dm

L_(dm) = 8.298 dm

The final result is:

829.8 mm → 8.298 dm

We conclude that 829.8 millimeters is equivalent to 8.298 decimeters:

829.8 millimeters = 8.298 decimeters

Alternative conversion
