Conversion formula
How to convert 40 feet to decimeters?

We know (by definition) that: 1 ft = 3.048 dm.

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

1 ft / 40 ft = 3.048 dm / x dm

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

x dm = (40 ft / 1 ft) * 3.048 dm → x dm = 121.92 dm

Conclusion:

40 ft = 121.92 dm
