Unit Converter
A complete, auto-updating unit converter for length, weight, temperature, area, volume, speed, time, and digital storage — all in one place.
Length Conversion
=
1
Formula:
value_in_to_unit = value × (from_factor ÷ to_factor)
Example: 1 meter = 3.28084 feet.
Weight / Mass Conversion
=
1
Formula:
value × (from_factor ÷ to_factor)
Example: 1 kg = 2.20462 lb.
Temperature Conversion
=
32 °F
Formulas:
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
Area Conversion
=
1
Formula:
value × (from_factor ÷ to_factor)
Volume Conversion
=
1
Formula:
value × (from_factor ÷ to_factor)
Speed Conversion
=
1
Formula:
value × (from_factor ÷ to_factor)
Digital Storage Conversion
=
1
Formula:
value × (1024ⁿ difference between units)
How this Unit Converter Works
This converter uses standard metric and imperial conversion factors to instantly transform one unit into another. Temperature uses mathematical formulas instead of multiplication factors.
General Conversion Formula
Converted Value = Input Value × (From_Unit_Factor ÷ To_Unit_Factor)
Temperature Conversion Formulas
°F = (°C × 9/5) + 32°C = (°F − 32) × 5/9K = °C + 273.15
Examples
- 1 meter = 100 centimeters
- 1 kilogram = 2.20462 pounds
- 0°C = 32°F
- 1 liter = 0.264 gallons
Input Rules
- Inputs must be numeric (decimals allowed).
- Negative values allowed for temperature only.
- Unit selections must be valid conversions within the group.
- Large numbers (up to trillions) are supported.
Frequently Asked Questions
It uses standardized conversion factors used in scientific, engineering, and commercial applications.
Computers use binary measurement, so each step is 1024 (2^10), unlike metric units (×1000).
Temperature scales do not share a common zero point, so simple multiplication cannot be used.
