How results are calculated
Each tool applies standard conversion factors between selected units. Values update as you type. For medical dosing, legal metrology, or safety-critical specs, verify against authoritative references—online converters are productivity aids, not certified instruments.
Tools in this category
Length Converter
Convert meters, feet, miles, inches, and nautical miles for travel, drawings, and homework—factors update as you type.
Weight Converter
Convert pounds, kilograms, ounces, and stones for luggage and kitchen scales. Not a medical dosing tool.
Temperature
Switch Celsius, Fahrenheit, and Kelvin for weather, cooking, and science—free, instant.
Volume
Switch liters, gallons, cups, and cubic meters for recipes, fuel, and tank estimates. Not a dosing calculator.
Area
Convert square feet, square meters, acres, and hectares for flooring and lots. This is area math, not a GIS projection transform.
Speed
Convert mph, km/h, m/s, and knots for travel and weather. Aviation paperwork still needs the published factor.
Time
Convert seconds, minutes, hours, and days of duration—not time zones or calendar dates.
Bytes / Bits
Convert bits, bytes, KB, MB, GB, and TB. Check whether you mean 1000 (SI) or 1024 (binary) when a disk label is ambiguous.
Mass
Convert kilograms, grams, and slugs for science labs—use this when you need SI mass rather than kitchen-scale weight.
Density
Convert density units such as kg/m³, g/cm³, g/ml, lb/ft³, slugs/ft³, and lb/gal.
Pressure
Convert pascals, bar, psi, and torr for HVAC and lab notes. Not a substitute for ASME stamp tables.
Energy
Move between joules, calories, kilowatt-hours, and BTU for homework and bills—check food Calorie vs calorie scale.
Power
Convert watts, kilowatts, and horsepower. Note mechanical vs electrical horsepower when a spec sheet is ambiguous.
Force
Convert newtons, pound-force, and kilogram-force for statics problems and spec sheets.
Fuel Economy
Compare US MPG and L/100 km without mixing the inverse scales. Use the same fuel type when you compare vehicles.
Frequency
Convert hertz, kilohertz, megahertz, and RPM for audio, radio, and motor notes—do not mix RPM with Hz without the 2π/60 factor.
Angle
Convert degrees, radians, gradians, and mils for trig homework and aiming tables—confirm which mil definition you need.
Astronomical Units
Convert AU, light-years, and parsecs for classroom astronomy. Rounded factors are not spacecraft navigation.
