## How to convert from feet+inches to millimeters?

To convert from feet+inches to millimeters, we can start by converting feet to inches. For this, we have to multiply the number of feet by 12.

Then we add the result with the initial number of inches to find the total number of inches. Finally, we multiply the total number of inches by 25.4 to find the number of millimeters.

#### Example 1:

Determine the number of millimeters that are equal to 2 feet + 5 inches.

We start by converting feet to inches. Therefore, we multiply 2 by 12 to get 24.

Then we add the 24 inches to the 5 inches given initially to get a total of 29 inches.

Now, we multiply the total number of inches by 25.4 to get the number of millimeters

d(mm) = 29Γ25.4

d(mm) = 736.6 mm

#### Example 2:

How many millimeters equal 3 feet + 7 inches?

Letβs convert the number of feet to inches by multiplying by 12. Therefore, we have 3Γ12=36.

Now, we add the inches and we have: 36+7=43.

Multiplying the number of inches by 25.4, we have:

d(mm) = 43Γ25.4

d(mm) = 1092.2 mm

#### Example 3:

Find the number of millimeters that are equal to 5 feet + 3 inches.

Letβs find the number of inches by multiplying the number of feet by 12. Therefore, we have: 5Γ12=60.

Adding the number of inches, we have: 60+3=63.

Multiplying the number of inches by 25.4, we have:

d(mm) = 63Γ25.4

d(mm) = 1600.2 mm
