To convert 100 millimeters (mm) to inches, we need to understand the conversion factor between these two units of measurement. The metric system defines 1 inch as equal to 25.4 millimeters. This conversion factor allows us to calculate the equivalent of any measurement in millimeters to inches by dividing the number of millimeters by 25.4.
Conversion Process
The process of converting 100 mm to inches involves a simple division. We take the 100 mm and divide it by 25.4 mm/inch to find out how many inches it is equal to. The formula looks like this: inches = 100 mm / 25.4 mm/inch.
Performing the Calculation
When we perform the calculation, we get: inches = 100 / 25.4 = 3.937007874015748 inches. This result tells us that 100 mm is approximately equal to 3.94 inches when rounded to two decimal places.
| Measurement in mm | Equivalent in Inches |
|---|---|
| 100 mm | 3.94 inches |
