I wish it did the conversion for you. You have to know how many seconds to dose your fluid to get the right amount of dosing. This also means a manual calibration. I just set it to go at 50% until it hit 100ml. That took 160 seconds, so 1.6 seconds per ml. Turning the flow down will make more exact small doses. Turning up for larger dosing with less precision. There is no option for half seconds. So if I was dosing 1ml per day I would either have to do 1 second and under dose. Or two seconds and over dose with a 50% power setting. Way easier if I could calibrate and set it to hit certain ml doses after entering my manual speed setting within the app.
