Saw on internet some equations to convert from frequency in hertz to mph. Some equations need a gear ratio while others do not. I found the equation mph = circumference * RPM * 60. Now, it makes sense and if use dimensional analysis I found 1Hz = 60 RPM and 60Hz = 3600 RPM. When calculated for a diameter of a motor shaft wit
