I would assume so too, grams is the usual measurement for reptiles etc, and I can't imagine any other measurement that would make sense in that number. I definitely would go above .3 then. I usually only do .1 per 50 grams, so .2 makes sense, adding the extra .1 because of her severely low bone density and the fact she laid eggs. Depending on how much weight she gains when she is a bit more stable I would likely back her down to .2 as a maintenance dose. Then again I don't know what they mix their liquid calcium to. Most exotic vets I have gone to do the measurements I have learned but XD it can always differ. Usually with female veileds I always have liquid calcium on hand (especially if they have shown past issues with mbd or bone density) because it is amazingly useful at the end of laying for a few days and at the beginning for the two days before laying.
