What is the simmering temperature in thermometer? I would like to know the simmering temperature what is when we simmering food.

I just purchased a food thermometer and would like to learn how to use it.
There is no exact temperature, but consensus is that the temperature needs to be below the boiling point of 100 °C / 212 °F and above the poaching temperature of 82 °C / 180 °F.
