Conversion Formulas
Result = Value × (From Unit to Base) × (Base to To Unit)
Where:
- Value = The numerical value you want to convert
- From Unit to Base = Conversion factor from the source unit to the base unit
- Base to To Unit = Conversion factor from the base unit to the target unit
Example Calculation
Converting 100 centimeters to inches:
When traveling internationally, you might need to convert between metric and imperial units for measurements.
Given:
- Value = 100
- From Unit = centimeters (cm)
- To Unit = inches (in)
Calculation:
1 cm = 0.393701 inches
100 cm × 0.393701 = 39.3701 inches
Result: 100 centimeters = 39.37 inches
