I heard someone say that they had a ton of testing to do to me recently as they entered another weekly test cycle, and I pondered whether testing could be measured in tons. And since mass and energy are irrevocably connected, I wondered whether it could be true, as we are happy to talk about the energy expended in testing.
The standard definition of a kilogram changed late last year from the physical platinum prototype kept under lock and key near Paris, to a calculated value based on Planck's constant. With this new definition of the kilogram, a precise definition of Planck’s constant is required, 6.626070150×10−34 Joule-seconds. So does it help to plagiarise his equation for our purposes?
