Celsius-Fahrenheit Converter

Four ways to convert from Celsius to Fahrenheit:

Divide by 5, multiply by 9, then add 32.

Multiply by 18, divide by 10, then add 32.

Multiply by 10, subtract original temperature, divide by 5, then add 32.

Multiply by 10, subtract original temperature, double it, divide by 10, then add 32. So, converting 10°C using the first formula: 10/5=2, 2x9=18, 18+32=50°F

Three ways to convert from Fahrenheit to Celsius:

Subtract 32, divide by 9, then multiply by 5.

Subtract 32, divide by 3, multiply by 5, divide by 3.

Subtract 32, divide by 3, multiply by 10, divide by 6. So, converting 212°F using the first formula: 212-32=180, 180/9=20, 20x5=100°C
