temperature conversion

I had an argument with my boyfriend. He states that the reason why people use figure 32 in the simple conversion formula (when I take Farenheit, substract 32, then the result divide by 2, that's how I get Celsium), is that 32 in Farenheit = 0 Celsium. Is that true? Could anyone explain this conversion system? What's the scientific meaning of this?

The formula to convert from Fahrenheit to Celsius is (5/9)*(deg F-32) while the formula to convert from Celsius to Fahrenheit is (1.8*deg C)+32.

Examples:

1) 72 degrees Fahrenheit = __ degrees Celsius
(72 - 32) * 5/9 degrees Celsius
40 * 5/9 degrees Celsius
22.22 degrees Celsius

2) 212 degrees Fahrenheit = __ degrees Celsius
(212 - 32) * 5/9 degrees Celsius
180 * 5/9 degrees Celsius
100 degrees Celsius

3) 0 degrees Celsius = __ degrees Fahrenheit
(0 * 1.8) + 32 degrees Fahrenheit
0 + 32 degrees Fahrenheit
32 degrees Fahrenheit

4) 72 degrees Celsius = __ degrees Fahrenheit
(72 * 1.8) + 32 degrees Fahrenheit
129.6 + 32 degrees Fahrenheit
161.6 degrees Fahrenheit

I hope this helps!
