What is the formula to convert Celsius to Fahrenheit?
°F = (1.8 × °C) + 32
°F = (°C + 32) × 1.8
°F = (°C × 1.8) - 32
°F = (°C - 32) / 1.8
Convert 20°C to Fahrenheit using the formula °F = (1.8 × °C) + 32. What is the result?
58°F
68°F
78°F
88°F
What is the formula to convert Fahrenheit to Celsius?
°C = (°F - 32) ÷ 1.8
°C = (°F + 32) × 1.8
°C = (°F - 32) × 1.8
°C = (°F + 32) ÷ 1.8
Convert 392°F to Celsius using the formula °C = (°F - 32) ÷ 1.8. What is the result?
100°C
150°C
200°C
250°C
