The risky part of local anesthetic dosing is the unit switch. You draw it up in percent and milliliters, the ceiling lives in milligrams per kilogram, and the patient's safe maximum depends on lean weight, not the number on the chart. Three conversions, one of them easy to get wrong by a factor of ten.
The local anesthetic dose calculator keeps all of it in one place. Pick the agent, set the concentration, dial the volume in milliliters or milligrams, and it shows the dose as a percentage of that drug's maximum for the patient in front of you.
Because the ceiling is figured on lean weight and adjusts for epinephrine, the percentage you see is the real margin, not an optimistic one. Watch it climb as you add volume and you know exactly how much room is left before you stop.
