A factor that needs to be considered is how you took your temperature. If you measured your temperature under your armpit then 99°F or higher indicates a fever. Temperature measured rectally or in the ear is a fever at 100.4°F (38°C) or greater. An oral temperature of 100°F (37.8° C) or more is a fever.

Why mercury is used in thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
