Length and Distance Converter

Metric to imperial and back, without the mental math

A European bike route in kilometers, a laptop sold by the centimeter, a recipe from abroad that measures a pan in millimeters: switching systems in your head is where mistakes happen. Jood's length converter works between eight units: meter, kilometer, centimeter, millimeter, mile, yard, foot and inch.

How to use it

1. Enter the value. Both a dot and a comma work as the decimal mark: 3.5 or 3,5.
2. Choose the unit you are converting from and the one you are converting to.
3. Click "Start Now". The result shows up to four decimal places.

Examples worked out with the tool

• A 15.6-inch laptop screen measures 39.624 cm across.
• 6 feet is 1.8288 m, and 180 cm is 5.9055 feet.
• A 10K race is 6.2137 miles, and one mile is 1.6093 km.

The factors are the official international definitions: an inch is exactly 2.54 cm, a foot 30.48 cm and a mile 1,609.344 m. Only the displayed result is rounded to four decimals; the calculation itself keeps full precision.

Feet and inches together

Heights are usually written in feet and inches, like 5 ft 11 in, while the tool gives decimal feet: 180 cm comes out as 5.9055 ft. To get the familiar format, convert to inches instead: 180 cm is 70.8661 inches. Divide by 12 and you get 5 feet with about 10.9 inches left over, so roughly 5 ft 11 in.

Results use a comma for thousands and a dot for decimals, so a mile shows as 1,609.344 m.

Where you will run into these units

• Spec sheets: screens, phones and TVs are measured in inches almost everywhere.
• Aviation: cruising altitude is given in feet, and 35,000 feet is 10.668 km.
• Sport: a marathon is 42.195 km, or 26.2188 miles, and a football field is 100 yards, or 91.44 m.
• Shopping abroad: furniture and luggage dimensions in centimeters on European sites.
