-40C = -40F

Also 0lbs does not equal 0kg when there’s no gravity.

huh?

Mass doesnt change with gravity

[–] ramenshaman@lemmy.world 15 points 5 days ago* (last edited 5 days ago) (1 children)

Typically, lbs is not mass, it's weight/force.

[–] FiskFisk33@startrek.website 11 points 5 days ago* (last edited 5 days ago) (1 children)

isn't that lbf?

The pund itself is defined as 0.45359237 Kg

[–] ramenshaman@lemmy.world 7 points 5 days ago (1 children)

Lbs can be lbf or lbm, but usually is referring to lbf, which is 0.4536 kg at 1g.

[–] FiskFisk33@startrek.website 8 points 5 days ago

when comparing to kg I will assume the mass unit, since comparing a mass value to a force has no meaning.

And temperature doesn't change with pressure

[–] Lemminary@lemmy.world 2 points 5 days ago

I'm not sure if you're joking, but it does. PV=nRT

[–] expatriado@lemmy.world 9 points 5 days ago (1 children)

no mass multiplied with gravity still results in no force, 0 Lb = 0 Kg; 0 Lbf = 0 N

[–] ch00f@lemmy.world 6 points 5 days ago

Yes, but 1kg also results in no force, so it's a trivial statement.

Gravity? What does that have to do with mass

[–] SpaceNoodle@lemmy.world 3 points 5 days ago* (last edited 5 days ago) (3 children)

Nothing in this context, but it can have a lot to do with force, for which pounds is the US customary unit.

[–] FiskFisk33@startrek.website 10 points 5 days ago

when compared to a value in Kg, the only logical interpretation is the mass pound. If it were lbf, the si unit conversion would be Newtons.

Having the same name for two different, but easily mixed up units is really annoying haha

[–] madjo@feddit.nl 0 points 5 days ago (1 children)

It's clear from context clues that they don't mean Force. As kilograms are an indicator of mass, not force. It's not our fault that US' imperial system is silly.

[–] SpaceNoodle@lemmy.world 0 points 5 days ago (1 children)

Imperial is a British thing, and the quantities differ significantly from US customary.

Nope. As I said, the US customarily uses US customary units. They ARE NOT identical to "Imperial" units, despite the coincidental naming.
