Q

If a thermometer reads 850 °F, what is the equivalent temperature in °C?

🔍 Key Concepts

• Fahrenheit–Celsius conversion formula • Order of operations when applying the formula (subtract, then multiply, then divide or vice versa) • Reasonable size of temperatures in °C for very high °F values

💭 Think About

• What is the standard formula to convert a temperature from °F to °C? Plug 850 °F into that formula step by step on paper. • After you apply the formula, is your result closer to hundreds of °C or thousands of °C? Eliminate any choices that are clearly unreasonable. • Estimate first: 32 °F is 0 °C and every 180 °F equals 100 °C. About how many 180 °F intervals fit into 850 °F, and what rough °C value does that suggest?

✅ Before You Answer

• Write out the full conversion formula: (°F − 32) × 5/9 = °C and check you are subtracting 32 from the Fahrenheit value, not something else. • Be sure you multiply by 5/9, not 9/5. • After calculating, check whether the chosen option is a realistic Celsius temperature for something extremely hot (think furnace temperatures).
