Revolutions per Hour to Revolutions per Second Converter

Revolutions per hour (rph) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one hour. It's used for very slow rotational systems and astronomical observations.

RPH became useful for describing very slow rotational systems such as astronomical observations, large industrial equipment, and systems where rotational speeds are extremely low. It provided appropriate scaling for applications where RPM would result in very small decimal numbers.

RPH is used for astronomical observations (planetary rotation), very slow industrial processes, large rotating equipment, and systems with extremely low rotational speeds. It's found in astronomical calculations and specifications for very slow rotating machinery.

Revolutions per second (rps) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one second. It provides a more direct relationship to the hertz unit for rotational measurements.

RPS developed as a scientific alternative to RPM, providing a direct conversion to hertz (1 rps = 1 Hz for rotational motion). It became important in scientific and engineering applications where SI units were preferred over traditional mechanical units.

RPS is used in scientific applications, high-speed machinery, precision instruments, and engineering calculations where direct conversion to hertz is beneficial. It's found in centrifuge specifications, high-speed motor ratings, and scientific equipment.
