Body-temperature notes follow the common clinical convention (fever ≥ 100.4 °F / 38.0 °C). Readings vary with thermometer type and time of day — general information, not medical advice.

What this reading means

102.0°F (38.9°C) is a fever. Anything from 100.4°F (38.0°C) up to about 102.2°F (39°C) is generally classed as a fever. Rest and fluids are the usual first steps; how the person feels and any other symptoms usually matter more than the exact number.

Measurement method changes the number, too: forehead and ear readings can differ from oral, and rectal readings (used for infants) tend to run a little higher. For the same person, a 0.5–1°F difference between methods is normal.

How to convert °F to °C

The exact formula is °C = (°F − 32) × 5/9. For 102.0°F: (102.0 − 32) × 5/9 = 70.0 × 5/9 = 38.9°C. To go the other way, °F = (°C × 9/5) + 32. A quick mental shortcut for Fahrenheit to Celsius: subtract 30 and halve it — close enough for a rough idea, though not exact.
