With thermometers
At a temperature of -40 (minus forty) degrees, the Celsius and Fahrenheit scales read the same number.

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
The property measured by a thermometer is temperature. Thermometers can detect and display temperature readings in various units such as Celsius or Fahrenheit.
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
Celsius and Fahrenheit thermometers will read the same temperature at -40 degrees, as -40 degrees Celsius is equal to -40 degrees Fahrenheit.
Thermometers may be calibrated in degrees Fahrenheit or degrees Celsius.
The instruments used in all temperature measurement are Thermometers. Fahrenheit and Celsius are just two different scales of temperature measure.The conversions are:Celsius to Fahrenheit:[°C] = ([°F] − 32) × 5⁄9Fahrenheit to Celsius:[°F] = [°C] × 9⁄5 + 32
Thermometers can be calibrated to measure temperature in Celsius, Fahrenheit, or Kelvin. Most common thermometers used for everyday purposes usually measure temperature in Celsius.
At -40.
clinical thermometers measure temperature in Celsius.
