20°C equals 68°F. The formula is: °F = (°C × 9/5) + 32, so 20 × 1.8 + 32 = 68.
A pleasant European summer day (22–25°C) corresponds to 72–77°F. Most Americans consider 75–80°F ideal summer weather.
At −40 degrees. That is the only point where −40°C = −40°F — the sole intersection of both scales.
Rule of thumb: double the °C and add 30. Example: 20°C × 2 + 30 = 70°F (exact: 68°F). The error is at most 2–3 degrees.
