Unit Conversion
Unit conversion involves converting measurements from one unit to another in both the Metric and English systems.
Metric System
- Based on multiples of 10
- Units are related by powers of 10
- Common units:
- Length: meter (m), centimeter (cm), millimeter (mm), kilometer (km)
- Weight/Mass: gram (g), kilogram (kg), milligram (mg)
- Volume: liter (L), milliliter (mL)
English System
- Also known as the US Customary System
- Units are not always related by powers of 10
- Common units:
- Length: inch (in), foot (ft), yard (yd), mile (mi)
- Weight/Mass: pound (lb), ounce (oz)
- Volume: fluid ounce (fl oz), cup (c), pint (pt), quart (qt), gallon (gal)
Conversion Between Systems
- Length:
- 1 inch (in) = 2.54 centimeters (cm)
- 1 foot (ft) = 30.48 centimeters (cm)
- 1 yard (yd) = 0.9144 meters (m)
- Weight/Mass:
- 1 pound (lb) = 0.453592 kilograms (kg)
- 1 ounce (oz) = 28.35 grams (g)
- Volume:
- 1 fluid ounce (fl oz) = 29.6 milliliters (mL)
- 1 cup (c) = 236.6 milliliters (mL)
- 1 pint (pt) = 568 milliliters (mL)
- 1 quart (qt) = 1.136 liters (L)
- 1 gallon (gal) = 3.785 liters (L)
Conversion Steps
- Identify the unit you want to convert from and the unit you want to convert to.
- Determine the conversion factor between the two units.
- Multiply the original value by the conversion factor.
- Simplify the result to the desired unit.
