One of the earliest temperature gauge was published by Giuseppe Biancani and was known as a thermoscope in 1617. Gabriel Fahrenheit was the one who invented the first modern thermometer.
To measure temperature. A gauge can be used instead of a thermometer, and is generally used in industry where a thermometer might be too fragile
If you mean the temp. Gauge in a CAR; it let's you know the temperature of the water in the engine Radiator. If the temp. Gauge is at, or close to, or past the RED mark on the gauge, then the water is TOO HOT which means that it is boiling and turning to steam and most likely to burst one of the rubber hoses that carry the water through the engine casing. It is very very unwise to keep the engine going if the gauge goes to the red mark on it. You will cause expensive damage to the engine if it is not kept cool by the water being circulated by the fan in the front of the engine. Just stop the engine and call a mechanic instantly.

Check coolant level Could be thermostat opening and closing due to engine coolant temperature flutuation
The answer depends on which gauge you are asking about: if it is a thermometer, it could be used to measure the oven temperature. If it is part of a clock/programmer, it tells the time of day and can be used to switch the oven on and off automatically.

Why does your temperature gauge rise and lower only when you have the heat on?
An automobile temperature gauge can fluctuate when the thermostat is opening and closing erratically. The temperature gauge can also fluctuate when the ground wire is loose.
It is possible that the temperature gauge has stopped working in a 1992 Tempo due to a blown fuse. It is also possible that the temperature gauge stopped working do to the temperature sensor in the engine having a short.
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
It will usually run with a gauge temperature of around 200-210 degrees.
