The paper deals with a specific type of tilt measurements, where an axial tilt is to be determined. The measurements are realized by means of accelerometers - MEMS devices most preferably. Various mathematical relations between the axial tilt and the Cartesian components of the gravitational acceleration are presented. Each relation is described in detail, especially in the terms of the resultant uncertainty of the measurement, as well as the requirements regarding the employed accelerometers. Results of experimental studies realized by means of commercial MEMS accelerometers are presented and discussed, especially with regard to the measurement accuracy that has been evaluated for each mathematical relation. Scope of application of each relation is proposed.
