30°C to Fahrenheit

86°F

30°C = 86°F = 303.15 K

Working: (30 × 9/5) + 32 = 86

30 degrees Celsius converts to 86 degrees Fahrenheit.

To convert Celsius to Fahrenheit, multiply by 9/5 (which is 1.8) and then add 32. For 30°C: 30 × 1.8 = 54, and 54 + 32 = 86. Going the other way, subtract 32 from the Fahrenheit value and multiply by 5/9.

If you only need a rough figure, double the Celsius number and add 30 — that gives 90°F here, which is 4 degrees off the exact 86°F. The shortcut is accurate enough for weather but not for cooking or medical use.

Thirty degrees is properly hot weather in temperate countries and an ordinary summer day in warmer ones. It is also a common washing machine setting: modern detergents are formulated to work at 30°C, and the dial is marked in Celsius even on machines sold in the United States.
