ⓘAbout This Conversion
- 1 Millimetre (mm) = 0.001 Metre (m)
- 1 Metre (m) = 1,000 Millimetres (mm)
Conversions are calculated in your browser. No values or files are uploaded.
For standardised measurement definitions, you can also refer to the International System of Units (SI), maintained internationally and explained by the National Institute of Standards and Technology.
Available Unit Conversion Categories
Our online unit converter supports several engineering and everyday measurement categories.
1. Length Conversion
Length conversion is commonly required in engineering, construction, manufacturing and education. Convert between millimetres, centimetres, metres, kilometres, micrometres, nanometres, inches, feet, yards, miles and other supported units.
For example:
- 1 metre = 100 centimetres
- 1 kilometre = 1,000 metres
- 1 inch = 25.4 millimetres
2. Mass and Weight Conversion
Convert mass measurements between milligrams, grams, kilograms, tonnes, pounds and ounces. These conversions are useful in laboratories, manufacturing, transportation, packaging and everyday calculations.
For example, 1 kilogram is approximately equal to 2.20462 pounds.
3. Temperature Conversion
Temperature conversion is important in scientific experiments, industrial processes, weather measurements and engineering applications.
Convert between Celsius, Fahrenheit and Kelvin.
Common formulas include:
- Fahrenheit = (Celsius × 9/5) + 32
- Kelvin = Celsius + 273.15
4. Area and Volume Conversion
Area conversion is useful in land measurement, construction, architecture and industrial planning. Convert between square millimetres, square centimetres, square metres, hectares and acres.
Volume conversion helps with liquid measurements, tank capacity, storage and process calculations. Supported units include millilitres, litres, cubic metres and gallons.
5. Speed and Time Conversion
Convert speed measurements such as metres per second, kilometres per hour, miles per hour and knots.
The time converter helps you change milliseconds, seconds, minutes, hours and days into other supported time units.
These conversions are useful in transportation, machine cycle-time calculations, production planning and scientific applications.
6. Pressure, Energy and Power Conversion
Engineering calculations frequently require different units of pressure, energy and power.
Use the converter for supported units such as:
- Pressure: Pascal, kilopascal, megapascal, bar and PSI.
- Energy: Joule, kilojoule, calorie and kilowatt-hour.
- Power: Watt, kilowatt and horsepower.
These measurements are particularly relevant to mechanical engineering, electrical systems, fluid mechanics and industrial equipment.
7. Force, Torque and Density Conversion
Force, torque and density are important parameters in mechanical design and manufacturing.
Convert between Newton, kilonewton, kilogram-force and pound-force for force measurements. Torque conversions include Newton-metre, Newton-centimetre and pound-foot. Density conversions include kilograms per cubic metre and grams per cubic centimetre.
8. Data Storage and Angle Conversion
The converter also covers digital storage measurements such as bits, bytes, kilobytes, megabytes, gigabytes and terabytes, along with their supported binary units.
For angular measurements, convert between degrees, radians and gradians. These units are commonly used in mathematics, geometry, robotics and mechanical engineering.

What Are Significant Digits in Unit Conversion?
Significant digits represent the meaningful digits used to express the precision of a numerical value.
For example, the value 2.50 contains three significant digits, whereas 2.5 contains two. Selecting an appropriate number of significant digits helps control how precisely a converted result is displayed.
For scientific and engineering calculations, selecting suitable precision is important. However, displaying more digits does not necessarily mean that the original measurement is more accurate.
