Conversion formula

The conversion factor from inches to decimeters is 0.254, which means that 1 inch is equal to 0.254 decimeters:

1 in = 0.254 dm

To convert 1 inch into decimeters we have to multiply 1 by the conversion factor in order to get the length amount from inches to decimeters. We can also form a simple proportion to calculate the result:

1 in → 0.254 dm

1 in → L_(dm)

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

L_(dm) = 1 in × 0.254 dm

L_(dm) = 0.254 dm

The final result is:

1 in → 0.254 dm

We conclude that 1 inch is equivalent to 0.254 decimeters:

1 inch = 0.254 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 3.9370078740157 × 1 inch.

Another way is saying that 1 inch is equal to 1 ÷ 3.9370078740157 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one inch is approximately zero point two five four decimeters:

1 in ≅ 0.254 dm

An alternative is also that one decimeter is approximately three point nine three seven times one inch.
