I guess you have played "dont starve" given the game design. The very simple system they use works fine for that setting.
If you want to make it more complicated that works of course, but why is 10 000 max? Seems arbitrary. Will it be shown to the player? Then use 0-100 or some other more understandable number. Adding more zeroes usually just annoys the player. If you want higher precision show decimals (when needed), but dont clutter the screen with useless information (such as super high precision).
If only used internally, why not use 0-1 for this meter? (1 usually means full).
