A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.
Considering this, are you supposed to add a degree to a temporal thermometer?
A temporal thermometer will read at about 0.5 to 1 degree lower than an oral thermometer, so you need to add 0.5 to 1 degree to get what your temperature would read orally. For example, if your forehead temperature read as 98.5°F, you could actually have a low-grade fever of 99.5°F or higher.
Also question is, do forehead thermometers work on temples?
You place them on the temporal artery, a blood vessel that runs across the forehead and sits just below the skin. Depending on the temporal thermometer, you can either point it directly at one spot on the forehead or roll it from the middle of the forehead to the temple.
Is forehead thermometer accurate?
For general use at home, forehead thermometers will give an idea of whether or not an individual has a fever. However, according to a 2020 study, forehead thermometers are less accurate than other methods of reading temperature, such as oral, rectal, or tympanic (ear) temperature readings.
An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature. A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Forehead (Temporal Artery) Temperature: How to Take
This thermometer reads the heat waves coming off the temporal artery. This blood vessel runs across the forehead just below the skin. Place the sensor head at the center of the forehead. Slowly slide the thermometer across the forehead toward the top of the ear.
At times, you can expect larger differences from temperatures taken at other body sites. This is because of two main reasons: Temporal artery temperature changes faster than a temperature taken rectally. Temporal artery temperature is not affected by the things that cause oral and underarm temperatures to be misleading …
