What is a Unit Converter?

A unit converter is a tool that converts measurements from one unit to another within the same physical quantity. Our free online unit converter handles length, weight, temperature, volume, speed, area, pressure, energy, data storage, and many other measurement categories — making it the only conversion tool you need.

Common Unit Conversions

• Length: km to miles (1 km = 0.621 miles), meters to feet (1 m = 3.281 ft), cm to inches (1 cm = 0.394 in)
• Weight: kg to pounds (1 kg = 2.205 lbs), grams to ounces (1 g = 0.035 oz)
• Temperature: Celsius to Fahrenheit (°F = °C × 9/5 + 32), Celsius to Kelvin (K = °C + 273.15)
• Volume: liters to gallons (1 L = 0.264 US gallons), ml to cups (240 ml = 1 cup)
• Speed: km/h to mph (1 km/h = 0.621 mph), m/s to km/h (1 m/s = 3.6 km/h)

Metric vs Imperial System

The metric system (SI units) is used by most countries worldwide and in all scientific work. The imperial system is primarily used in the United States, Myanmar, and Liberia for everyday measurements. India officially uses the metric system. Understanding both systems is important for international communication, travel, cooking recipes from foreign sources, and understanding American product specifications.

Temperature Conversion – Celsius vs Fahrenheit vs Kelvin

Celsius is used in most countries for weather and everyday temperature. Fahrenheit is used in the USA. Kelvin is the scientific standard where 0K is absolute zero (the coldest possible temperature, −273.15°C). Water freezes at 0°C = 32°F = 273.15K and boils at 100°C = 212°F = 373.15K. Human body temperature is 37°C = 98.6°F.

Data Storage Unit Converter

In the digital world, understanding data units is essential. 1 Kilobyte (KB) = 1,024 Bytes. 1 Megabyte (MB) = 1,024 KB. 1 Gigabyte (GB) = 1,024 MB. 1 Terabyte (TB) = 1,024 GB. Internet speed is measured in Megabits per second (Mbps) — note that 1 Byte = 8 bits, so a 100 Mbps connection downloads at about 12.5 MB per second.
