    • mL and cc are the same thing.
    • 1 Liter is equal to 1dm³ (which no one uses really but it doesn’t matter since the equivalency is at mL = cc
    • a grain of rice is about 0.02 gr so idk where you got that from. Weights were manufactured originally as was the meter (platinum cylinder and bar respectively, the originals are still in a museum in Paris)
    • weight is now based off the Planck constant and the meter is based off the speed of light. (2019)
    • Calorie, while metric is not an SI unit, that would be the joule.
    • the SI uses a hodgepodge of units and not all metric, they are however, all based off of natural constants.
    • A yard is just as arbitrary as anything else, it was a rod made somewhere around the 1500’s and was kept in London. Nowadays much like any other imperial unit, the sizes are based off their metric counterparts. is 1yd = 0.9144m exactly.
    • Metric time has been attempted (1000 ticks in a day) didn’t work super well. But like I said theres a ton of non metric units in the SI.
