Ships have engines, which generate movement points. This movement rate is used to move X sectors (squares/hexes) on the system map in a turn. To move between systems, you move into a sector containing a warp point, then use a move point to warp into the sector in the connected system containing the other end of that warp point. Combat movement is based off of strategic movement. In SE4, it is related by the function floor((m + 1) / 2), aka divide by two and round up. In SE5, things get harrier, and the relation involves converting the move value into distance moved in each time increment (on the order of 50 ms or something).
