Length, Weight and Temperature Converter

Convert length, weight, and temperature.

A CLEAR START

What this tool does

The Unit Converter changes values between supported units of length, weight and temperature. Choose the measurement category, source unit and target unit before calculating. Length and weight use conversion factors; temperature may also need an offset. This tool does not convert area, volume, speed, time or currencies.

Input: Value, measurement and units
Output: Converted value
Important limit: Length, weight and temperature only

1 metre → feet

EXPECTED RESULT

3.28083989501 ft

The displayed result is rounded to 12 significant digits.

Illustrative example. Your result depends on your input and the settings you choose.

Match the measurement type before entering a value

Metres and feet describe length, while kilograms and pounds describe weight in this workspace. They cannot be converted into each other without additional information about the object. Choose the correct category rather than treating a familiar number as interchangeable across measurement types.

Example: convert a length and a temperature

One metre corresponds to approximately 3.28083989501 feet in the displayed result. For temperature, 0 degrees Celsius corresponds to 32 degrees Fahrenheit, not zero. This illustrates why a temperature conversion cannot always be performed by multiplying by one factor. Use the correct source and target selections for each case.

Round only as much as the task allows

The workspace rounds displayed numeric results to 12 significant digits. A converted measurement is not more accurate than the original measurement itself. Keep units with the result, and apply any task-specific rounding at the end. This tool does not determine tolerances, validate an instrument or choose the measurement standard required by a project.

COMMON QUESTIONS

Unit converter: useful answers

Can this convert area, volume, or currencies?

No. This version covers length, weight, and temperature only. Currency rates and additional measurement groups are not included.

Why do temperature conversions differ from length conversions?

Some temperature scales need an offset as well as a scale factor. The tool applies the appropriate conversion for its listed units.

Which units are included?

Length includes metres, kilometres, centimetres, millimetres, inches, feet, yards and miles. Weight includes kilograms, grams, milligrams, pounds and ounces. Temperature includes Celsius, Fahrenheit and Kelvin.

Can I convert a room's square metres into square feet?

Not with this length converter. Area uses squared conversion factors and needs an area-specific calculation rather than treating square metres as ordinary metres.
