List the formula for Celcius ⇉ Farenheit
°F = [(9/5) x °C) + 32]
If my patient’s temp is 96.8°F, what is it in °C?
94°F?
96.8ºF ⇉ 36°C
94ºF ⇉ 34.5°C
What is the formula for Farenheit ⇉ Celcius?
°C = [(5/9) x (°F - 32)]
If my patients temp is 38°C, what is it in °F?
40°C?
38°C ⇉ 100 °F
40°C ⇉ 104 °F
A nice pattern to help do quick temp conversions.
- If you start at 95°F - celcius is 35.
- As you increase in 0.9°F, each °C goes up by 0.5°
