  • OK or Okay: (informal). Interjection indicating agreement to approval of what

    Somebody said or done, also indicating that something is finished, and

    No further action is to be taken.

    Origin: O. for Optimum (Latin) the best or the most favorable. And,

    K. (Chem.). A Symbol for equilibrium constant; the state reached

    In a reversible reaction velocities in the two opposing directions

    Are equal, so that the system has no further tendency to change.

    (Chambers Science and Technology Dictionary).

    The O. and the K. were used after double checking a formula, or a product, in order to indicate that it has passed. After the first test the O. For Optimum, was used to indicate that the formula passed. Then the K. was shown indicating ( for no further action is needed) Therefore when the symbol (OK) appeared in front of a formula it indicated that it has been double checked, and it is passed.
