Simple Formula for Conversion

Miles to Kilometers: Multiply the number of miles by 1.609344.
Example: 10 miles × 1.609344 = 16.09344 kilometers.
Kilometers to Miles: Divide the number of kilometers by 1.609344.
Example: 10 kilometers ÷ 1.609344 = 6.21371 miles.
Feet to Meters: Multiply the number of feet by 0.3048.
Example: 10 feet × 0.3048 = 3.048 meters.
Meters to Feet: Divide the number of meters by 0.3048.
Example: 10 meters ÷ 0.3048 = 32.8084 feet.
Inches to Centimeters: Multiply the number of inches by 2.54.
Example: 10 inches × 2.54 = 25.4 centimeters.
Centimeters to Inches: Divide the number of centimeters by 2.54.
Example: 10 centimeters ÷ 2.54 = 3.93701 inches.
Pounds to Kilograms: Multiply the number of pounds by 0.453592.
Example: 10 pounds × 0.453592 = 4.53592 kilograms.
Kilograms to Pounds: Divide the number of kilograms by 0.453592.
Example: 10 kilograms ÷ 0.453592 = 22.0462 pounds.
Celsius to Fahrenheit: Multiply the Celsius temperature by 1.8 and add 32.
Example: 20°C × 1.8 + 32 = 68°F.
Fahrenheit to Celsius: Subtract 32 from the Fahrenheit temperature, then divide by 1.8.
Example: 68°F – 32 = 36; 36 ÷ 1.8 = 20°C.
