How to Convert Meters, Feet, Kilometers, and Miles Online

Length conversions come up when working with measurements from different countries, product specifications, travel distances, construction plans, and everyday calculations. This guide explains the most common relationships between meters, kilometers, feet, and miles and shows how to convert them quickly.

Which length units does ToolAlto support?

The ToolAlto Unit Converter currently supports four common length units: meters, kilometers, feet, and miles. You can convert between any two of these length units. The same tool also supports Celsius and Fahrenheit for temperature, but length and temperature conversions are kept separate.

Common length conversion relationships

These relationships are useful when you want to understand what a conversion means:

• 1 kilometer = 1,000 meters.
• 1 meter = 3.280839895 feet.
• 1 mile = 1,609.344 meters.
• 1 mile = 5,280 feet.

Because the relationships between these units are fixed, a converter can calculate the equivalent value without needing a live data source.

How to convert meters to feet

To convert meters to feet, multiply the number of meters by 3.280839895. For example, 5 meters is about 16.4042 feet.

For a quick calculation, enter the value in the Unit Converter, choose meters as the source unit, choose feet as the destination unit, and select Convert.

How to convert feet to meters

To convert feet to meters, divide the number of feet by 3.280839895. Another way to express the same relationship is to multiply feet by 0.3048.

For example, 10 feet equals 3.048 meters.

How to convert kilometers to miles

To convert kilometers to miles, multiply kilometers by approximately 0.621371. For example, 10 kilometers is about 6.21371 miles.

For the reverse conversion, multiply miles by 1.609344 to get meters or use the converter directly for a kilometers-to-miles result.

How to convert miles to kilometers

To convert miles to kilometers, multiply the number of miles by 1.609344. For example, 5 miles equals 8.04672 kilometers.

This can be useful when a distance is given in miles but you need a metric measurement.

When should you use meters, kilometers, feet, or miles?

The right unit depends on the context. Meters are commonly used for relatively short measurements in the metric system, while kilometers are useful for longer distances. Feet are common in many everyday and building measurements in the United States and some other countries. Miles are commonly used for road and travel distances in the United States and a few other places.

When comparing two measurements, converting both to the same unit can make the comparison much easier.

Why can the displayed answer have more or fewer decimals?

A conversion can produce a decimal result even when the original measurement is a whole number. ToolAlto displays length results to six decimal places for readability. The displayed number is a formatted representation of the calculation, so it may contain trailing zeros or be rounded at the displayed precision.

What about temperature conversions?

The Unit Converter also supports Celsius and Fahrenheit. Temperature conversion uses different formulas from length conversion. For example, Celsius to Fahrenheit uses °F = (°C × 9/5) + 32, while Fahrenheit to Celsius uses °C = (°F − 32) × 5/9.

If you need a temperature conversion, select Celsius or Fahrenheit rather than mixing temperature with a length unit.
