Can a Regular Thermometer Be Used for Water

However, you should never, ever use a digital thermometer used to take body temperature to measure water. Those thermometers are built to measure body heat, which is cooler than the heat of boiling water. If you put it in a pot of hot water, it might shatter and seriously injure someone.

Can you use a thermometer for water?

Insert the probe of your thermometer into the water, and wait until the reading stabilizes. This will give you a good indication of the temperature of the water you showered in. A mercury thermometer would work, if you could still find one.

How do you measure the temperature of water?

Water temperature can be measured with a thermistor, which is a metallic device that undergoes a predictable change in resistance in response to temperature changes. This resistance is measured and converted to a temperature reading in Celsius, Fahrenheit, or Kelvin.
