The Watt-hour is a "UI hack" that hides the conflict between base-10 math and base-60 time. It forces us to multiply a rate (Watts) by time to get energy, only to divide back by time to understand flow.

I propose a unit shift to align physics with human scheduling: The Jot (Jt ), defined as 1 Joule/hour.

It shifts the awkward math (1 hr=3600 s) out of the usage calculation and onto the device rating.

    Conversion: 1 Watt = 3.6 kiloJots (kJt ).

    Usage Math: A 50 kJt  bulb running for 10 hours uses exactly 500 kJ. No conversion factors.

    Battery Math: Capacity (Joules) / Rate (Jots) = Time (Hours). Pure integer division.

This post argues for killing the Watt-hour, measuring energy in Petajoules, and measuring power in Jots.

1 case: 14w * 1h -> 0.014kWh * 40p of total cost. There is nothing complex.

2 case: It's an issue with mAh markings. Battery rated in Wh has same simple math.

There are no consumer issues jot solves. More over additional ~10^3 magnitude is consumer hostile.
