To use the converter, type the number you want to convert in the box. Then select the unit you are converting from and the unit you want to convert to. Click the "Convert" button, and the result will appear below. You can try different values and units as many times as you like. All the conversions you made will be displayed in the Conversion History section.
Metric Length Units
The metric system is used in most of the world. It is based on powers of ten. That means each unit is either 10 times bigger or 10 times smaller than the next. This makes it easy to convert between units. To convert, you move the decimal point left or right depending on whether you’re going to a larger or a smaller unit. Common metric length units are millimeters (mm), centimeters (cm), meters (m), and kilometers (km).
For example: 1 meter = 100 centimeters = 1000 millimeters. To change meters to kilometers, you divide by 1000. So, 5000 meters = 5 kilometers.
Imperial Length Units
The imperial system is mostly used in the United Kingdom and other English speaking countries. Common length units include inches, feet, yards, and miles. The system is not based on tens, so conversions are less simple compared to metric.
For example: 1 foot = 12 inches, 1 yard = 3 feet, and 1 mile = 1760 yards.
US Customary Length Units
The United States uses the US customary system, which is similar to the imperial system but not always the same. The main units are inches, feet, yards, and miles, just like imperial. However, some units differ slightly in definition.
These are specific to the US customary system (Imperial doesn’t use them):
- Rod (also called pole or perch, US survey) → 16.5 survey feet.
- Chain (US survey) → 66 survey feet.
- Furlong (US survey) → 660 survey feet.
These are mostly used in land surveying and older legal land descriptions in the U.S., not in everyday life.
