What this means

This is the comfortable room-temperature band. 68–72 °F (20–22 °C) is the usual indoor thermostat range.

Room temperature ≈ 68–72 °F (20–22 °C)
Mild day ≈ 75 °F (24 °C)

The math, step by step

Subtract 32 from the Fahrenheit value: 70 − 32 = 38.
Multiply by 5/9: 38 × 5/9 = 21.11 °C.

Formula

°C = (°F − 32) × 5/9

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8). The Fahrenheit scale sets water's freezing point at 32° and boiling at 212°, while Celsius uses 0° and 100°.
