You'd be surprised at how correct this statement probably is."Officially" being the key word. Behind the scenes they're just eye balling things, busting out the duct tape.

The are many units of pressure in metric, but the SI unit is Pascals. Other popular ones are Atmospheres, Barr, Torr and mmHg. The point being that you can convert quickly, easily and intuitively between them.Please tell me the unit of pressure of the metric system? Or the insistence on using mg/kg instead of ppm (when thinking of a concentration, it is not the same thing).

So the hard part about figuring out the power of a pump is... the units? The advantage is occasionally the equations you use do not need a factor. Although most of them still do, you just use a different factor. And in engineering the only difference is when you click on the excel cell and look at the top formula bar there are extra numbers in the rare case you need to know what the equation is actually doing...
And the US is always giving handouts or slowing up to let other countries be equal, so NASA is just playing nice. Please tell me the unit of pressure of the metric system? Or the insistence on using mg/kg instead of ppm (when thinking of a concentration, it is not the same thing).

Concentration can be in many forms, that you can switch between easily. Generally I just see ppm, but ppm is the exact same thing as mg/kg. Having it in mg/kg simply makes unit conversion simple. I generally use mol/L in the lab, because I'm not working at nano scales.
Metric is great! So easy to convert units, and very intuitive. Imperial is not.

kegs buys his duct tape by the meter but don't let on, he'll get mad!
English equivalent:
kegs purchases his gaffa tape by the metre but please do not tell him so, he will cop a strop!
Quick conversion for you :nod:
What is the viscosity of the liquid or the angle of repose?
...if you think about it, all measurements are dumb anyway. Don't you guys still have your original meter stick over in Europe? I know the definition changed to some lame interpretation about the speed of light (imagine trying to check your rulers with that!). Over here we have the official teaspoon (called Obama's Teaspoon) and the official foot. I hope to be the next official foot, it's a perfect 12" long.
...That's what she said.
