To convert a temperature from Celsius to Fahrenheit, you can use the following formula:

°F = (°C × 9/5) + 32

Substituting 4-8 Celsius into the formula, we have:

°F = (4-8 °C × 9/5) + 32

°F = ((4-8) × 9/5) + 32

°F = (-4) × 9/5 + 32

°F = -7.2 + 32

°F = 24.8

Therefore, 4-8 Celsius is equal to 24.8-39.2 Fahrenheit.
