Advertisements
Solution
Two scales of temperature are
(i) Celsius (ii) Fahrenheit
Relation:
Water Freezes at 0°C or 32°F and boils at 100°C or 212°F
∴ (212-32) °F = (100-0)° C
180° F = 100° C
1° F = `(5/9)` °C
or 1°C = `(9/5)` °F or `("C"-0)/(100-0) = ("F"-32)/(212-32)`
or `"C"/100 = ("F"-32)/180` or `"C"/5=("F"-32)/9`
