How It Works: Conversion Formulas & Real Examples
Our unit converter calculator uses precise, standardized conversion factors to transform values between units. Below are the formulas and real worked examples for all our main conversion cases:
1. Length Conversions (feet to meter, cm to inch, feet to cm, meter to cm):
• feet to meter formula: Meters = Feet ÷ 3.28084 (or Feet × 0.3048)
Example: 10 feet × 0.3048 = 3.048 meters.
• cm to inch formula: Inches = Centimeters ÷ 2.54
Example: 10 cm ÷ 2.54 = 3.937 inches.
• feet to cm formula: Centimeters = Feet × 30.48
Example: 6 feet × 30.48 = 182.88 cm.
• meter to cm formula: Centimeters = Meters × 100
Example: 1.75 meters × 100 = 175 cm.
2. Weight / Mass Conversions (kg to lbs, lbs to kg, gram to kg, kg to gram, stone to kg):
• kg to lbs formula: Pounds = Kilograms × 2.20462
Example: 5 kg × 2.20462 = 11.023 lbs.
• lbs to kg formula: Kilograms = Pounds ÷ 2.20462 (or Pounds × 0.453592)
Example: 150 lbs × 0.453592 = 68.038 kg.
• gram to kg formula: Kilograms = Grams ÷ 1000
Example: 500 grams ÷ 1000 = 0.5 kg.
• kg to gram formula: Grams = Kilograms × 1000
Example: 2 kg × 1000 = 2000 grams.
• stone to kg formula: Kilograms = Stone × 6.35029
Example: 10 stone × 6.35029 = 63.503 kg.
3. Temperature Conversions (celsius to fahrenheit, kelvin to celsius):
• celsius to fahrenheit formula: Fahrenheit = (Celsius × 9/5) + 32
Example: (25°C × 1.8) + 32 = 77°F.
• kelvin to celsius formula: Celsius = Kelvin - 273.15
Example: 300 K - 273.15 = 26.85°C.
4. Area Conversions (sq ft to sq meter):
• sq ft to sq meter formula: Sq Meters = Sq Feet × 0.092903
Example: 500 sq ft × 0.092903 = 46.452 sq meters.
5. Volume Conversions (liter to gallon, gallon to liter, ml to liter):
• liter to gallon formula: Gallons = Liters × 0.264172
Example: 10 liters × 0.264172 = 2.642 gallons.
• gallon to liter formula: Liters = Gallons × 3.78541
Example: 5 gallons × 3.78541 = 18.927 liters.
• ml to liter formula: Liters = Milliliters ÷ 1000
Example: 750 ml ÷ 1000 = 0.75 liters.
