Question:medium

The temperature of a body shown by a faulty Celsius thermometer is 49 °C and by a correct Fahrenheit thermometer is 122 °F. The correction to be applied to the faulty thermometer is

Show Hint

Distinguish between "error" and "correction". Error is how much the measurement is off (\(\text{True} - \text{Measured}\)). Correction is what you must add to the measurement to fix it (\(\text{Correction} = -\text{Error}\)). In this case, the error is -1°C (it reads 1°C too low), so the correction is +1°C.
