Quick Answer
30 °F = -1.111111 °C
Rounded: 30 °F ≈ -1.1 °C
Exact formula
°C = (°F − 32) × 5/9
(30 − 32) × 5/9 = -1.111111 °C
30 °F → -1.111111 °C
In everyday terms
Below freezing. Below freezing for water at standard pressure.
- •Ice and frost are possible, especially with wind and moisture.
- •Winter layers are often needed (coat, hat, gloves depending on wind).
