The main difference between a regular mercury thermometer and an electronic digital thermometer is that the former requires you to read the temperature from a liquid inside it, while the latter has a display screen which shows the exact temperature. Another difference is in accuracy; an electronic thermometer is more accurate than a mercury thermometer because it does not require you to add any liquids or chemicals to it to calculate the temperature. Additionally, some electronic thermometers can measure the temperature of multiple objects at once, whereas a mercury thermometer only measures one object at a time.
