Since pF means $1 \times 10^{-12}\text{F}$ and µF means $1 \times 10^{-6}\text{F}$, move the decimal point from the pico-Farads value 6 places to the left to get the value in micro-Farads

$$22000\text{pF} \Rightarrow .022\mu\text{F}$$

#### Fahrenheit to Celsius

$$C = (F - 32) \times (\frac{5}{9}) = \frac{(F - 32)}{1.8}$$

#### Celsius to Fahrenheit

$$F = \frac{9}{5} \times C = 1.8C + 32$$
