subtract   32   from   the   Fahrenheit   and   divide   the remainder by 1.8. Examples: 1. F = l.8C + 32 Given:   24°C. Find: °F 24 × 1.8 = 43.2 43.2 + 32 = 75.2 or 75°F. 2. C = F 32 1.8 - Given:   96°F. Find: °C. 96 – 32 = 64 64 + 1.8 = 35.5 or 36°C To change a Celsius reading to an absolute value, add   the   Celsius   reading   to   273°   algebraically.   For example, to find the absolute value of -35°C, you would add minus 35° to 273°K algebraically. That is, you take 273° and combine 35° so you use the minus (-) function to arrive at 238°K. To  change  a  Fahrenheit  reading  to  an  absolute value,   first   convert   the   Fahrenheit   reading   to   its equivalent Celsius value.   Add this value algebraically to   273°.   Consequently,   50°F   is   equivalent   to   2830 absolute,  arrived  at  by  converting  50°F  to  10°C  and then adding the Celsius value algebraically to 273°.
