I think amp-hours are confusing and I wish they just gave us battery life figures in joules

Welcome to the Unpopular Opinion community!
How voting works:
Vote the opposite of the norm.
If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.
Guidelines:
Tag your post, if possible (not required)
- If your post is a "General" unpopular opinion, start the subject with [GENERAL].
- If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].
Rules:
1. NO POLITICS
Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.
2. Be civil.
Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry. Please also refrain from gatekeeping others' opinions.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Shitposts and memes are allowed but...
Only until they prove to be a problem. They can and will be removed at moderator discretion.
5. No trolling.
This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.
6. Defend your opinion
This is a bit of a mix of rules 4 and 5 to help foster higher quality posts. You are expected to defend your unpopular opinion in the post body. We don't expect a whole manifesto (please, no manifestos), but you should at least provide some details as to why you hold the position you do.
Instance-wide rules always apply. https://legal.lemmy.world/tos/

Then why joules?
Watthours is another already fairly common unit.
1Wh lasts for one hour at one watt. Half and hour at two watts. And so on.
Amps are directly related. You can get the amps from the wattage, by dividing the watt with the voltage being run.
Watthours are stupid. You're taking the SI unit of energy, the joule, dividing it by time to get watts, and then multiplying it by a different unit of time to get energy at a different conversion rate. It's ludicrous! I have a philosophical opposition to such confusing units.
Or, think of it as just adding time to watts.
If a thing uses 100 watts. Then in one hour, it used 100Wh.
It's literally the simplest unit for this.
That's not addition, it's multiplication.
...
Adding. As in combining. Introudcing. Attaching. Affixing.
Not math.
Well, you gonna love freedom units
Actually I think of amp-hours as an imperial unit. They feel the same as imperial units.
