Abstract: A weighing apparatus includes a level gauge, a weight sensor, a accelerometer configured to detect acceleration changes of two axes of x, y on a virtual horizontal plane of the weight sensor, a storage unit configured to store reference outputs of the two axes of the accelerometer when the weight sensor is horizontal and at a reference position and temperature, and an arithmetic processing unit, where the level gauge includes a light emitting unit configured to make the inside luminescent, the arithmetic processing unit compares current outputs of the accelerometer of the weighing apparatus with the reference outputs, and detects an output change occurring in the x and/or y as a tilt of the weighing apparatus, and the light emitting unit is configured to be capable of switching between a first operation mode when the weighing apparatus is horizontal and a second operation mode when a tilt is detected.
