1. Celsius and Kelvin scale are used for all low & high temperature readings. 2.Fahrenheit is mostly used for low temperatures in clinical thermometers or a little lower or higher temperature readings
With thermometers
Scientific comparisons are done in Celsius, but outdoor readings are still announced, (and body temperatures still recorded) as temperatures on the Fahrenheit scale.
same size and shape
Thermometers may be calibrated in degrees Fahrenheit or degrees Celsius.
Formula: Fahrenheit = (Celsius x 1.8) + 32
At -40.
clinical thermometers measure temperature in Celsius.
Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.
