Introduction to Inches and Centimeters
Before diving into the specifics of how to convert 1.25 inch to cm, let’s take a moment to understand the two units of measurement we’re working with: inches and centimeters.
- Inches: A unit of length commonly used in the United States and other countries that don’t use the metric system. Inches are often used to measure things like height, screen size, and objects that are part of a larger system of imperial measurements.
- Centimeters (cm): Part of the metric system, which is used almost everywhere in the world. A centimeter is a smaller unit of length, and it’s a part of the meter (1 cm = 1/100 of a meter). In contrast to inches, the metric system is based on powers of 10, making conversions straightforward.
The key to converting between these two units is knowing the exact conversion factor: 1 inch = 2.54 cm.
