This isn't just an approximation; since 1959, the international inch has been defined as exactly 25.4 millimeters, which equals exactly 2.54 centimeters. Quick Conversion Formulas
The (inches, feet, yards) originated from traditional British units, often based on the dimensions of the human body. The Metric system (millimeters, centimeters, meters) was designed in France during the late 18th century to be a decimal-based system, making it much easier to scale by powers of 10. inch to centimeter
A few millimeters can ruin a structural fit. This isn't just an approximation; since 1959, the
If you have a calculator handy, the math is straightforward: A few millimeters can ruin a structural fit
Multiply the number of inches by 2.54 . Example: 10 inches × 2.54 = 25.4 cm
Today, only three countries—the United States, Liberia, and Myanmar—do not use the metric system as their official system of measurement. Tips for Mental Math
