Type either side; the other updates. Everyday temperature conversion without a weather-app detour.
F = C × 9/5 + 32. C = (F − 32) × 5/9. Exact linear maps — no wind chill or heat index.
Not a medical device conversion chart and not Kelvin/Rankine (unless those fields appear). For lab work, use calibrated instruments.
