You know there's something wrong with US politics when NASA is forced to communicate in Imperial measurements.

"Orion’s main engine provides up to 6,000 pounds of thrust, enough to accelerate a car from 0 to 60 mph in about 2.7 seconds. At the time of the burn, Orion’s mass was 58,000 pounds and burned approximately 1,000 pounds of fuel during the firing."

Artemis II Flight Day 2: Orion Completes TLI Burn, Crew Begins Journey to the Moon - NASA

NASA’s Artemis II crew is on the way to the Moon.

OFFS "On the station, crews rely on more than 4,000 pounds of exercise hardware spread across roughly 850 cubic feet." 🙄

NASA's use of Imperial measurements is similar to if US biologists started using species names in the Texas dialect instead of in Latin.

I can't overstate this. NASA's use of pounds and cubic feet in its outreach efforts does not come across to science-literate people, inside or outside the US, as a sign that the country is a badass superpower that can do what it likes and ignore everyone else.

Instead it suggests that the US is a provincial nation of dungaree-wearing banjo players.

@mrundkvist It is frustrating as well for the hundreds of millions of Americans who had no choice of measurement standards in school or everyday life, most of whom neither wear dungarees nor play banjo. Every day I am applying complex conversion formulae just to get by in Mexico. I still don't have an innate sense of either metric sizes or celsius temperatures. Metric is easier, but still a struggle. Poor me.

@farbel @mrundkvist I mean, it's not like we don't have inches and feet in Europe either. I've had to do conversions all my life too because they're commonly used in many contexts. Since the default is metric, I do the conversion the other way of course, but at the end of the day, it's still an additional cognitive load.

I was just discussing wind speed with my brother, who works at an airport. I'm used to metres per second wind speeds, but they use knots.

@veronica @farbel @mrundkvist in Europe? After Brexit? Ireland is (fairly) metric since 2005, isn’t it?

@Tho99 @veronica @farbel @mrundkvist

Ah, aviation...

Altitude is still measured in Flight Levels which are enumerated in thousands of feet (though they're actually a pressure altitude). Even metric flight levels in Russia named that way though the actual altitude varies slightly because of the difference between the metric flight levels and everybody else's feet-based flight levels. So planes may have to adjust their altitude slightly when entering or leaving Russia.

@resuna @Tho99 @farbel @mrundkvist I can think of at least 5 areas for myself. I grew up around boats, and they're still referred to in feet. I've also been around carpentry all my life and although everything is sold in millimetres, it's still often referred to as 2by4, 2by6, 4 inch nails, etc. In my church going days I did sound engineering, where everything is in inches, and I worked in electronics where it's all decimal inches. I also worked in IT where hardware is all inches as well.
@veronica @resuna @Tho99 @mrundkvist I worked with a Swiss carpenter in Tucson for a couple years as his helper. He would use inches, but 1 1/8 would be 1.1. 1 3/16 would be 1.15. Drove me crazy at first, but I got used to it.

@veronica @resuna @Tho99 @farbel @mrundkvist
A 2x4 is 1½ x 3½ inches
A 2x6 is 1½ x 5½ inches

My old house had an addition built by someone who didn't know that, and as a result there's an approximately 1-inch jog where one wall of the addition meets the original house.

@veronica @resuna @Tho99 @farbel @mrundkvist Unless it’s a racing sailboat, and then it’s in meters, which was very confusing.
