- StavrosK 10y ago"Oh wow, air pressure fell to almost zero, a person would suffocate in ther... Wait a minute, the ground unit is 940! This is a 6% difference!"
- zaroth 10y agoSometimes ground units reflect ground truths, even if the scale doesn't actually hit zero.
- thomasahle 10y agoYup, this is also why I like the metric version. With inches of quicksilver it's hard to know where zero is.
- nayuki 10y agoIt would be better if NOAA used kilopascal (an actual SI unit) instead of millibar, but I guess the conversion is not too bad since 1000 mbar = 100 kPa.
- Declanomous 10y agoThe NOAA data isn't consumed solely by scientists though. I'm sure millibars were chosen as the metric measurement of pressure because people actually use them, such as mariners.
- nickpeterson 10y agoJust the other day a last minute task at work put me under 500 millibars of pressure. I'll show myself out.
