Question 1

List the formula for Celcius ⇉ Farenheit

Answer 1

°F = [(9/5) x °C) + 32]

Question 2

94°F?

Answer 2

96.8ºF ⇉ 36°C
94ºF ⇉ 34.5°C

Question 3

What is the formula for Farenheit ⇉ Celcius?

Answer 3

°C = [(5/9) x (°F - 32)]

Question 4

If my patients temp is 38°C, what is it in °F?
40°C?

Answer 4

38°C ⇉ 100 °F
40°C ⇉ 104 °F

Question 5

A nice pattern to help do quick temp conversions.

Answer 5

1. If you start at 95°F - celcius is 35.
2. As you increase in 0.9°F, each °C goes up by 0.5°
