To convert -57 degrees Fahrenheit to Celsius, you can use the formula: C = (F – 32) x 5/9. Substituting -57 for F gives C = (-57 – 32) x 5/9 = -89.44 degrees Celsius. This conversion is crucial for international temperature standards and scientific calculations. In practical terms, it helps in weather forecasting, cooking, and determining appropriate clothing for different climates. Objects like freezers, winter environments, and cold storage facilities fall within this temperature range, making the conversion useful in various everyday situations.
