One time when I donated blood the bag was put on a metric scale. When the indication on the scale was something like 600 g they took it off, as it was done. Blood is heavier than water, and the bag has a mass too.

Did you ask them what pint that would be? 473 mL is a pint and 450 mL is what the bag holds. Just think you can become a gallon donor by giving only 3600 mL of blood instead of 3800 mL, a savings to you of 200 mL.

I was the first one in, and went to the booth to have the pre-donation discussion. The worker asked my weight [sic] and I told it to him in kilograms, telling him (truthfully) that I don't know it any other way. (The scale at home shows kg only.) He grumbled and did a somewhat incorrect, though flattering, conversion. And this was a medical person. Dang.

Easy! One reads it "1776 July 4". What's the problem? For a recent medical problem, I answered questions including my birthdate numerous times. I always said "1935 July 15" and no one ever asked me to clarify that. I don't delude myself; I think most of them wrote "July 15, 1935" but it certainly was not unclear to them the way I said it. I gave my height in centimetres and mass in kilograms, too, by the way.. No problem! Bill Hooper 74 kg body mass* Fernandina Beach, Florida, USA * plus or minus a kilogram or so.
