Step 1: Understand the conversion factors
The conversion factor for converting millimeters (mm) to inches (in) is 1 inch = 25.4 millimeters. This means that every inch is made up of 25.4 millimeters.
Step 2: Write down the conversion formula
The conversion formula for converting millimeters to inches is:
mm ÷ 25.4 = in
Step 3: Determine the value to be converted
Let’s say that we want to convert 50 millimeters to inches. So, the value of mm is 50 mm.
Step 4: Substitute the value in the conversion formula
Now, we will substitute the value of 50 mm in the conversion formula:
50 mm ÷ 25.4 = in
Step 5: Solve the equation
Using a calculator, we will divide 50 by 25.4, which gives us the answer 1.968503937 inches. This means that 50 millimeters is equivalent to 1.968503937 inches.
Step 6: Round the answer (optional)
If you want to round off the answer, you can use the appropriate rounding off method. For example, if you want the answer to be rounded to 2 decimal places, the answer would be 1.97 inches.
Step 7: Check your answer
To make sure that your answer is correct, you can use a unit converter or solve the equation using the reverse conversion factor. In this case, the reverse conversion factor would be:
in x 25.4 = mm
Substituting the value of 1.968503937 inches in the above equation gives us:
1.968503937 in x 25.4 = 50.00000005 mm
As you can see, the answer for this equation is very close to the original value of 50 mm, which means our calculation was correct.
Step 8: Repeat the process for other values
You can use the same steps to convert other values from millimeters to inches. Just remember to use the correct conversion formula and factor according to the given conversion units.
Congratulations! You have successfully converted millimeters to inches using the conversion formula and steps provided above.
