The conversion factor from liters to deciliters is 10, which means that 1 liter is equal to 10 deciliters:

1 L = 10 dL

To convert 640.9 liters into deciliters we have to multiply 640.9 by the conversion factor in order to get the volume amount from liters to deciliters. We can also form a simple proportion to calculate the result:

1 L → 10 dL

640.9 L → V_(dL)

Solve the above proportion to obtain the volume V in deciliters:

V_(dL) = 640.9 L × 10 dL

V_(dL) = 6409 dL

The final result is:

640.9 L → 6409 dL

We conclude that 640.9 liters is equivalent to 6409 deciliters:

640.9 liters = 6409 deciliters
