📐 About This Calculator
Each category has a base unit. Values convert through the base: multiply by the source factor, divide by the target factor. Temperature uses its own formulas.
GENERAL: result = value × factor[from] ÷ factor[to]
TEMPERATURE:
°C → °F: C × 9/5 + 32
°C → K: C + 273.15
Variable Definitions:
- • factor = Amount of the base unit per unit
✅ Best used for:
- • Everyday conversions
- • Science and engineering units
- • Cooking and travel
⚠️ Limitations:
- • Fuel economy conversion is inverse (km/L vs MPG)
- • Rounded to a sensible precision
📖 How Unit Conversion Works
Base-unit conversion
Within a category, every unit is defined relative to a base unit, so any-to-any conversion is a single multiply and divide.
Temperature is special
Temperature scales have offsets, not just factors, so Celsius/Fahrenheit/Kelvin use dedicated formulas.
