Ships traveling on water use Knots. Machs are a measurement of how fast space vehicles travel.
Indicated Mach number which is corrected for instrument and position errors equals True Mach Number Instrument errors are errors due to manufacturing or design defects that all instruments have to some small degree. Position error is due to the position of the pitot and static ports on the aircraft getting disturbed air pressure from some part of the aircraft's structure.
One knot is equal to 1.1.5078 miles her hour. 1 mile per hour is equal to 0.868976 knots. A knot dervives not from mph but latitude; it takes 1 minute of time to travel one minute of latitude.

Yes you can fly two flags on one pole all you have to do is make two knots each to the length of your flags and tie them to it or if you have clips on your pole clip the first flag to the top clip then clip your second flag to the bottom of the first one then place clip number 2 to the end of the 2nd flag then let it be chur

Mach 2 = 1,322.94 knots
Knots is a measurement of speed. Horsepower is a measurement of power. To obtain that speed on water is probably not possible. To obtain that speed in air takes allot of horsepower. That is over Mach 2 (twice the speed of sound),
5100.087 MPH 8207.795 KMPH 4431.885 Knots
Mach 0.89 or 950km/h or 512 knots
Mach 3, sounds good.728 knots
Knots or Mach for very fast ones
The maximum speed of the A380 is Mach 0.96 (634 mpg, 551 knots). max cruising speed = .85 MACH max design speed = .96 MACH
At cruise altitude (35,000ft) the average cruise speed is 460 knots - 530mph.
Subsonic means any speed below the speed of sound. (Mach 1). So subsonic aircraft range from 0 - 661 knots at sea level. (Mach 1 is 661 knots at sea level.)
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
Typical cruise speed is 470 knots (860KPH) or Mach 0.82
Maximum speed: Mach 1.8 , (1,191 knots, 2,205 km/h)
