Revolutions per day is frequency unit, symbol: [rpd]. Definition of 1 revolutions per day = Hz/86400. The number of events or cycles that occurred in one day. The sign rpd (revolutions per day) the value if Hertz / 86400. It is used to express slow frequencies. The Earth's rotational frequency is 1 rpd (revolution per day). Compared to hertz, revolutions per day is smaller unit.
• 1 [rpd] = (exactly) `1/86400` [Hz] = `1.15740740740741*10^-05` [Hz]
• 1 [Hz] = (exactly) `86400/1` [rpd] = 86400 [rpd]
