Conversion formula

The conversion factor from centimeters to decimeters is 0.1, which means that 1 centimeter is equal to 0.1 decimeters:

1 cm = 0.1 dm

To convert 77 centimeters into decimeters we have to multiply 77 by the conversion factor in order to get the length amount from centimeters to decimeters. We can also form a simple proportion to calculate the result:

1 cm → 0.1 dm

77 cm → L_(dm)

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

L_(dm) = 77 cm × 0.1 dm

L_(dm) = 7.7 dm

The final result is:

77 cm → 7.7 dm

We conclude that 77 centimeters is equivalent to 7.7 decimeters:

77 centimeters = 7.7 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.12987012987013 × 77 centimeters.

Another way is saying that 77 centimeters is equal to 1 ÷ 0.12987012987013 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that seventy-seven centimeters is approximately seven point seven decimeters:

77 cm ≅ 7.7 dm

An alternative is also that one decimeter is approximately zero point one three times seventy-seven centimeters.
