Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Huh? Whatchu talkin bout Willis?
Watt is a Joule per second
Volts, Amps, kWh, MJ... These are all metric.
Sssch don't tell the Americans or they will try to wrangle in BTU in nuclear power plants
WE INVENTED IT AND BUH GAWD, WE WILL MEASURE IT IN MURICA UNITS!
Ignore how nonsensical BTUs are: Gonna shove energy and weight into a single measurement and it changes based on the initial temperature of the water.
Or HVAC uses tons of ice needed to cool something. Euroguys probably don't have air conditioners, just that tilt window technology.
I do like the obscure AWG scale especially 0000
lol tilt windows
Y'all do know what BTU stands for, right?
British Thermal Units. It’s the energy needed to heat 1 lb of water 1 degree F.
The bad part is that no one bothered to set the starting temp of the water so there’s 5 separate standards for what the hell a BTU actually is, which makes it a really bad standard.
In a number of instances where there is not a standard in place already it is not uncommon to see metric measurements mixed with imperial or US customary measurements.
I’m not in any way shape or form claiming that ALL of it is mixed.
However what does actually happen is the a unit of measure might be mixed with a customary one and then that becomes the defacto measurement, you may see wire resistance shown as a mix of Ohms/1000ft.
I am not getting into an argument about the merits of metric, I’m on board, I am with you. That doesn’t mean there aren’t some silly oddballs.
Is their an imperial equivalent to ohm?
It might be the case that imperial resistance is ohm the same as metric. Metric uses ohm as it's constituent with base units of metric, but imperial doesn't abide by rules like that.
If you had to make a imperial equivalent to resistance, it would be a fraction of the resistance of the monarchs finger.
Until we actually electrocute a king there probably won’t be
There's no non metric electrical units except ohms/1000 ft or cross section dimensions, and AWG (and MCM kilo circular mils kcmils) versus mm^2
Why US uses awg with reverse scale instead of diameter is insane
formula: D(AWG) = 0.005·92^((36-AWG)/39) inch
Yeah electricity is weird because Americans use metric for it. And it’s that way because metric predates it
Fun fact: While metric predates our full understanding of electricity, our understanding of electricity played a key role in the definition of the SI units.
As I understand it, the reason the SI unit for mass is kg not g - making it an outlier to my mind - is so that electical engineers could keep volts and amperes as convenient numbers.
