Trying to measure ointment
Most ointments need no careful measurement. Some (Nitro, Nicotine, etc.) are applied by pre-measured patch or tape. Some come with special instructions indicating the number of inches of tip extrusion. However, a few (antibiotics, etc.) would benefit from a 'handy' measurement like FTU to help the user gauge or calculate each dose and calculate the doses available from the usually given but not directly usable measurements like net weight & concentration.
