Abstract: Provided is an apparatus for measuring acceleration and a tilt angle using thermal convection of a fluid which includes a container containing the fluid, a heating body including a first heating element and a second heating element arranged in the container and a crosspoint that is formed as end portions of the first and second heating elements are electrically connected, and radiating heat when current is applied through the other end portions of the first and second heating elements, and a thermocouple including a thermocouple junction that contacts the crosspoint of the heating body and being point-symmetric with the heating body with respect to the crosspoint of the heating body, wherein a voltage between both end portions of the thermocouple is measured to calculate a temperature of the crosspoint of the heating body.
