I really dont understand why though. It's like mixing up kilometers and kilometers per hour. I couldn't imagine a mental model of these units that would make them interchangeable.
- polshaw 14y agoBecause it is referred to as Rate X Time, whereas most things, like Km/KPH, are referred to as Quantity per Time. (which is more explicit) I'm sure no one would be confused by the difference between joules and joules per second.
- stcredzero 14y agoActually, I'm sure there are people who don't process the 'per' as more than a verbal convention with an abstract meaning, and who are somewhat confused about the entire notion of rate. They're probably pretty rare on HN, however.
