About Unit Conversion
Unit conversion is the process of expressing a quantity in different measurement units. The metric system (meters, kilograms, liters) is used worldwide, while the imperial system (feet, pounds, gallons) is primarily used in the United States. This tool provides instant, precise conversions seamlessly between both systems across six common categories spanning over forty specific units of measurement.
Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
Multiply by 9/5 then add 32. Formula: F = (C × 1.8) + 32. Quick landmarks: 0°C = 32°F (freezing), 20°C = 68°F (room temperature), 37°C = 98.6°F (body temperature), 100°C = 212°F (boiling).
How many kilometers are in a mile?
1 mile = 1.60934 kilometers. To convert miles to km, multiply by 1.609. To convert km to miles, multiply by 0.6214. Quick rule of thumb: multiply km by 0.6 for a rough miles estimate.
What is the difference between a megabyte and a mebibyte?
A megabyte (MB) in the SI standard is 1,000,000 bytes (10⁶). A mebibyte (MiB) is 1,048,576 bytes (2²⁰). Operating systems historically used 'MB' to mean mebibytes, which is why a '100 MB' file might show as 95.4 MB in Windows. Modern usage is converging on SI prefixes for storage marketing.
How do I convert pounds to kilograms?
Multiply pounds by 0.4536. Formula: kg = lbs × 0.4536. To go the other way: lbs = kg × 2.2046. Quick reference: 1 kg ≈ 2.2 lbs, 10 kg ≈ 22 lbs, 70 kg ≈ 154 lbs.
What is a knot in speed?
A knot is one nautical mile per hour. 1 knot = 1.852 km/h = 1.151 mph. It's the standard unit of speed in aviation and maritime navigation. A nautical mile is based on the circumference of the Earth: it equals one arcminute of latitude (1,852 metres).
