1000 millimeters in decimeters


1000 millimeters is equivalent to 10 decimeters.[1]

Conversion formula
How to convert 1000 millimeters to decimeters?

We know (by definition) that: 1mm = 0.01dm

We can set up a proportion to solve for the number of decimeters.

1 mm 1000 mm = 0.01 dm x dm

Now, we cross multiply to solve for our unknown x:

x dm = 1000 mm 1 mm * 0.01 dm x dm = 10.0 dm

Conclusion: 1000 mm = 10.0 dm

1000 millimeters is equivalent to 10 decimeters

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 0.1 times 1000 millimeters.

It can also be expressed as: 1000 millimeters is equal to 1 0.1 decimeters.


An approximate numerical result would be: one thousand millimeters is about zero decimeters, or alternatively, a decimeter is about zero times one thousand millimeters.


[1] The precision is 15 significant digits (fourteen digits to the right of the decimal point).
