It would depend on the size of the circular item you are rotating. Divide the circumference of the item ( in meters) into 272.23, and then multiply the answer by 60 seconds, to get rpm.
Mach 500 means 500 times the speed of sound. The speed of sound in air is somewhere around 350 meters/second. If you multiply that, you get approximately 175,000 meters/second, or 175 kilometers/second. Note that the speed of sound can vary, depending on several conditions.
Mach 3.32 is approximately 3.32 times the speed of sound in air. At sea level, where the speed of sound is around 343 meters per second (1,125 feet per second), Mach 3.32 translates to about 1,138 meters per second (3,740 feet per second). This speed is typically associated with high-performance military aircraft and supersonic vehicles.

Mach 6 is about 4,449.3 mph
Mach 1 is the speed of sound, which is 343 meters per second, or 343 m/s. Mach 8 is 8 times faster than the speed of sound . 8 X 343 2,744 m/s or 2.74 km/s
Mach 3.6 = 2,740.34 mph
Mach 6 is six times the speed of sound, which is approximately 2,300 meters per second (or 5,100 miles per hour). At Mach 6, an object would be traveling at around 6,917 meters per second (or 15,459 miles per hour).
Mach 500 means 500 times the speed of sound. The speed of sound in air is somewhere around 350 meters/second. If you multiply that, you get approximately 175,000 meters/second, or 175 kilometers/second. Note that the speed of sound can vary, depending on several conditions.
612.5 meters per sec
Supersonic speed is defined as speeds greater than the speed of sound, which is approximately 343 meters per second (767 mph) at sea level. Aircraft flying at supersonic speeds typically travel at speeds ranging from Mach 1 to Mach 5, or roughly 343 meters per second to 1716 meters per second.
Mach 0.87 is approximately 87% of the speed of sound in air. At sea level and at standard atmospheric conditions, the speed of sound is about 343 meters per second (1,125 feet per second), so Mach 0.87 would be around 299 meters per second (980 feet per second). This speed is commonly encountered in high-performance aircraft and is significantly faster than typical commercial jet speeds.
Mach one is the speed of sound, which is about 761.2 miles per hour (340.3 meters per second). Mach two is twice the speed of sound, which is about 1,522.4 miles per hour (680.6 meters per second).
1,126 ft/s
Mach 3.2 refers to traveling at 3.2 times the speed of sound. The speed of sound varies depending on altitude and temperature, but at sea level and room temperature, it is approximately 343 meters per second. Therefore, Mach 3.2 would be about 1,100 meters per second.
Mach 0.8-1.0
Mach 1.7 is equal to about 1294 mph.
