Quick Answer
25 °F = -3.888889 °C
Rounded: 25 °F ≈ -3.9 °C
Exact formula
°C = (°F − 32) × 5/9
(25 − 32) × 5/9 = -3.888889 °C
25 °F → -3.888889 °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).
