A method for determining the temperature of an away-facing surface (4) of an object (2), wherein at least one ultrasonic pulse (50) is transmitted through a surface (3) of the object facing a transmitter/receiver unit (S/E) into said object (2); the at least one ultrasonic pulse (50) is reflected at least partially in the direction of the transmitter/receiver unit (S/E) on the surface (4) of the object facing away from the transmitter/receiver unit (S/E); and the reflected part (70) of the at least one transmitted ultrasonic pulse (50) is received by the transmitter/receiver unit (S/E). At least one temperature value (M) for the object surface (3) facing the transmitter/receiver unit (S/E) is also determined; at least one value (L) is determined for the propagation time of the at least one ultrasonic pulse (50, 70) through the object (2), and at least one temperature value (T) for the object surface (4) facing away from the transmitter/receiver unit (S/E) is determined by means of the at least one temperature value (M) for the object surface (3) facing the transmitter/receiver unit (S/E) and the at least one propagation time value. The invention also relates to a corresponding measuring device for determining temperature. The invention further relates to a use of said method and to a use of the measuring device.
