How to get touch.position in Unity "units"?

Well, I'm making a 2d Game (Orthographic camera) and I want to instantiate objects where the screen is touched by the player. The thing is that the position that I get when I touch the player is in pixels for some reason... What can I do?

This is my code

 int fingerCount = 0;
         foreach (Touch touch in Input.touches) {
             if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled) {
                 fingerCount++;
             }
             if (fingerCount > 0) {
                 //crear huevo
 
                 print (touch.position.x + ", " + touch.position.y);
                 //Instantiate(huevo, new Vector3(touch.position.x, touch.position.y, 0), Quaternion.Euler(0, 0, 0));
             }
                 
         }
