Technically, yes. But measurements of weight, volume, and temperature are also part of the metric system, and those didn’t derive from the meter.
Seconds are also part of the metric system, but one of the few not based on decimal/base-10.
Again, I’m just speculating that the author used “metric” because it often represents decimal/base-10 measurements. Not really arguing whether they were technically correct in doing so.
- funcDropShadow 3y agoWeight and volume were defined based on the meter. Volume is just expressed in m³ or litre, which is just 1/1000 of 1 m³. Mass was originally defined such that 1 kg of water is the mass of one litre of pure water at sea level.
- anbende 3y agoThis isn't totally true. Mass and volume measurements were indeed derived from the meter. A gram is a cubic centimeter of water. A liter is 1/1000 of a cubic meter. Apparently Celsius is derived from Kelvin (really just translated so 0 is the freezing point of water), which is derived using metric units in a formula that is a bit beyond me but available here: https://www.bipm.org/en/si-base-units/kelvin https://www.bipm.org/en/si-base-units/kelvin Anyway, TIL.

For volume this is obvious nonsense since the metric system expresses volumes in … cubic meter! And even weight, a kilogram is “the weight of a liter of water” (that is a thousands of a cubic meter of water).
