About This Calculator
The meter is the SI base unit of length, but everyday use spans millimeters to kilometers and inches to miles depending on your location. Converting between metric and imperial units is one of the most common calculation needs in travel, construction, and science.
Formula
1 meter = 3.28084 ft = 39.3701 in = 0.001 km = 0.000621 miles
1 inch = 2.54 cm = 0.0254 m
Example Calculation
Convert 5 feet 9 inches to meters.
- Total inches = (5 × 12) + 9 = 69 inches
- Meters = 69 × 0.0254 = 1.7526 m
5 ft 9 in = 1.7526 meters
