The unit is GWh, the physical quantity it describes is “energy storage capacity”. Those two are not the same.
Take this example:
Unit: second, physical quantity: could be things like “time”, “specific impulse”, “distance” (light-second), etc. Many physical quantities can be measured in seconds.
- adament 4y agoIs it really true that you can measure distance in seconds? I think light-seconds are different units from seconds hence why they measure distances, similar to how Watt-hours and Watts are not the same unit. If a second was a measure of distance then speed would be unit-less (second / second) as opposed to the speed of light which is light-second / second ≈ 3e8 m/s.
- jupp0r 4y agoYou are right, light seconds don't fit in well. My point still stands, you can't really know what physical quantity is measured just from looking at the unit alone, that's now what units are made for.
