Answer :
Final answer:
The technician should use a digital thermometer that can measure temperatures in both Fahrenheit and Celsius to ensure convenience and reduce the likelihood of conversion errors.
Explanation:
If a technician needs to take temperatures in both Fahrenheit and Celsius using a digital thermometer, the most efficient method would be to use a digital thermometer that can measure temperatures in both Fahrenheit and Celsius. Modern digital thermometers often have the option to switch between these units of measurement, providing convenience and reducing the chance for manual conversion errors. While it is possible to use separate thermometers for Fahrenheit and Celsius measurements or to convert the temperatures manually, these methods are less practical and more time-consuming. Manual conversion is prone to mistakes, especially if the conversion factors are not applied correctly. To convert Fahrenheit to Celsius, you subtract 32 from the Fahrenheit temperature and divide by 1.8. Similarly, Celsius is converted to Fahrenheit by multiplying by 1.8 and then adding 32. The relationship between Fahrenheit and Celsius is important because it allows for accurate temperature readings in different units without the need for multiple thermometers. Knowing that -40°C is equal to -40°F can also act as a reference point when understanding these two scales.
