SI UNIT : metre/second2 CGS UNIT :cm/second2
Units of measurement are useful to rationally measure anything.
The units of measurement for rotational speed in an engine, commonly denoted as rpm, are revolutions per minute.
SI units is what we use in the United States for the common unit of measurement for matter.
Speed consists of distance over time. You have to use the same measures of distance and time or the comparison is meaningless. You have to agree on the units in advance, or you have to convert to them.
base on what you measure to use the metric units.

Neither of those units is a measurement of speed.
meters
You can't convert that. One is a distance measurement, the other is a speed measurement. If it is a speed problem, use the formula distance = speed x time. In this case, you need to know how long it takes to advance those 2.2 meters. You also need to convert all the units to compatible units first - for example, using meters for distance, seconds for time, and meters/second for speed.
I'm pretty sure knots use to be the measurement of wind speed. I'm not totally sure. Sorry.
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
You can use astronomical units or light years.
