How length conversion works
All lengths are converted through meters using exact, internationally agreed factors — the inch, foot, yard, and mile have been defined in metric terms since 1959, so there is no approximation in the math itself, only in the rounding you choose.
result = value × meters(from) ÷ meters(to)
Exact factors
| Unit | In meters |
|---|---|
| 1 inch | 0.0254 m (2.54 cm) |
| 1 foot | 0.3048 m |
| 1 yard | 0.9144 m |
| 1 mile | 1,609.344 m |
| 1 nautical mile | 1,852 m |
Worked examples
- 10 meters to feet — 10 ÷ 0.3048 = 32.81 ft.
- 5 km to miles — 5,000 ÷ 1,609.344 = 3.11 mi.
- 6 ft to centimeters — 6 × 30.48 = 182.88 cm.
When you need to convert lengths
- Travel — reading road signs in kilometers when you think in miles, or the reverse.
- DIY and building — following a plan in millimeters while your tape measure reads inches.
- Height — turning 5 ft 10 in into 178 cm for a form or a fitness app.
- Screens and print — matching a diagonal in inches to centimeters, or margins in mm to inches.
Quick reference
A handful of round conversions cover most everyday needs: 1 inch ≈ 2.5 cm, 1 foot ≈ 30 cm, 1 meter ≈ 3.28 ft, and 1 mile ≈ 1.6 km (so 5 miles ≈ 8 km). These are close enough for estimates; the calculator applies the exact 1959 factors when precision matters.

Length Converter — frequently asked questions
How many feet are in a meter?
One meter equals about 3.28084 feet, because a foot is defined as exactly 0.3048 meters. So 10 meters is roughly 32.81 feet.
How do I convert inches to centimeters?
Multiply by 2.54 — the inch is defined as exactly 2.54 cm. A 27-inch screen is 27 × 2.54 = 68.58 cm.
What is the difference between a mile and a nautical mile?
A statute mile is exactly 1,609.344 meters, while a nautical mile — used at sea and in aviation — is 1,852 meters, about 15% longer.
Are the conversion factors exact?
Yes. The converter uses the exact legal definitions (1 in = 0.0254 m, 1 ft = 0.3048 m, 1 yd = 0.9144 m, 1 mi = 1,609.344 m), so any rounding only happens at the precision you choose.
