How do they do it? They do it **poorly**.

I know what you’re asking is how do they actually make the calculations, and that is basically done by running a small electric current at a very low voltage through your skin and extrapolating a lot of other values based on a lot of assumptions. it’s very sensitive, not very accurate, and can be thrown off by things like sweaty feet and how much water you’ve had recently.
