Understanding standard conversion factors helps verify results and enables quick mental calculations:
| From | To | Multiply By |
|---|---|---|
| Meters | Feet | 3.28084 |
| Feet | Meters | 0.3048 |
| Centimeters | Inches | 0.393701 |
| Inches | Centimeters | 2.54 |
| Kilometers | Miles | 0.621371 |
| Miles | Kilometers | 1.60934 |
| Yards | Meters | 0.9144 |
| Meters | Yards | 1.09361 |
These factors derive from the international yard and pound agreement of 1959, which defined 1 yard as exactly 0.9144 meters. From this standard, all other imperial-metric length relationships calculate with mathematical precision.
For users who need to understand the mathematics behind conversions or perform manual calculations:
Meters to Feet: feet = meters × 3.28084 The meter, defined as the distance light travels in 1/299,792,458 of a second, converts to feet using this precise factor.
Centimeters to Inches: inches = centimeters ÷ 2.54 One inch equals exactly 2.54 centimeters by international agreement, making this conversion exact rather than approximate.
Kilometers to Miles: miles = kilometers × 0.621371 Since 1 mile equals 1,609.344 meters by definition, the kilometer-mile relationship follows mathematically.
Height Conversion (Meters to Feet-Inches): First multiply meters by 3.28084 for total feet, then separate whole feet from the decimal portion, multiply the decimal by 12 for inches.
