Notes on the household loads that actually move a power or water bill. Each page is a real article — typical watts or gallons, what people mix up, and a way to open the matching estimate in Whatt at your rate.
Start with Help if you want the math and how to read a bill. Start with About if you want what Whatt is and is not. The list below is one page per appliance or fixture, written so a search or an AdSense crawl sees more than an empty calculator shell.
These are not copies of one template with the title swapped. Each article is about that machine: typical watts or flow, the habit that actually moves the bill, and the mix-up people bring from a different appliance.
Usage estimate only — not a utility bill, load calc, or advice.
