Step-by-Step: -40 °C to °F

  1. Start with -40 °C
  2. Multiply by 9/5: -40 x 9/5 = -72
  3. Add 32: -72 + 32 = -40 °F

-40°C (-40°F) is below freezing — all standing water turns to ice. At this temperature, pipes are at risk, roads become icy, and wind chill makes it feel even colder. Proper winter clothing with insulated layers is essential for any outdoor exposure.

Did You Know?

At -40°C, car antifreeze is essential. Standard coolant protects down to about −37°C (−34°F).
