Alright, lets look at the US Customary Units and their definitions. Here is the section called "Mass and Weight". As you can see, everything is defined in metric units of mass. You won't find even pound-force to be part of the Customary units. I couldn't find any source saying that pound (not "pound-force") is a unit of force. However, there was an agreement (I think in 1955) to define the pound in kg.
it breifly at the end mentions "1 lb=0.45359237 kilogram" as well as "1 Newton=0.224809 pound force"
That basically implies that lb (pound, imperial unit) is a unit of mass and "pound-force" (non-imperial unit, part of the British Engineering Units) is a unit of force. Thus, pound (on its own) is a unit of mass, right?
Could you provide any source that states that a pound is a unit of force? Because the American National Standard Institute (here), aswell as Wikipedia and numerous other sources claim its a unit of mass.
A pound is actually not a unit of force. At least not in the US Customary System nor in the British Imperial System. They both are defined as units of mass. Both systems define the standard pound as the "avoirdupois pound", a unit of mass. The US Customary System doesnt even include a unit of force.
"Pound-mass" comes from the "English Engineering Units" which differentiates between pounds-mass and pounds-force.
"Pound" is not a unit of force in any current system. Its the standard unit of mass (slug is also a unit of mass but usually not used). Feel free to provide any source that states that pound is a unit of force.
Did you take into account that earth was heavier millions of years ago? Also, you would have to specify where on earth it weighed that amount.
Anyway, pound is an imperial unit for mass, just like slug.
The "pound-force" is not part of the imperial units, jut rather of the "English Engineering Units" that differentiate between pound-mass, pound-force, pound-foot and others.
"Pound" is not a unit of force in ANY system. If you really meant force (I doubt that) you should have used lbf. Anyway, noone cares how many Newtons of force the earth exhibited on that animal, all the metric-using people in this thread are interested in its mass. All scales used to weigh something display kg (or pounds), so units of mass.
In both the British Imperial System and the US Customary Units, a pound is a unit of mass, defined as 0.45359237 kg. In fact, all the definitions in the section "Weights and Masses" of the US Cusomaries are defined in either kg, g or mg.
We are not talking about the weight force here. We are simply converting pounds-mass to kg. If you dont believe OP meant the mass (whicg Im sure he certainly did) then aks him but when saying something weighs a certain amount then one is usually referring to its mass.
There are differenr methods but to name one, you have two particles very close to each other and then you bombard them with energy until they inevitably interact with each other and get entangled.
Lets say we wanna talk. I keep a private decryption key and send you a (public) encryption key. Everyone now knows how to encrypt a message for me but nobody, not even you, can read it. The decryption ley is NEVER SENT and kept secret, the encryption key is public but can never decrypt anything.
To put it simply, one party openly distributes keys that can ONLY ENCRYPT but not decrypt a message. So I can encrypt a message but only the original key distributor can decrypt it. Thats how a first secure communication is established that can then be used to exchange any initial secrets for further communication...
No liability. Got your food 2 hours late? Better yet: Didn't get your food at all? Guess you lost that money.
Pricing. If drivers are able to make their own prices, they will probably start undercutting each other, resulting in very low fees for the drivers. Also, it would be very intransparent to userd how much the delivery will cost.
What is a convenience store for? I always thought they were for areas with fewer supermarkets but why do I need a convenience store if I have a supermarket close?
I'm not sure I've ever been to an actual bar. Isn't it just a restaurant without the food? (There are a couple of restaurants near me that serve cocktails).
