It’s now possible to see your power as watts per a kilogram on the power curve.
You’ll first want to add your weight, and then you can click on the W/kg button at the top right of the graph and the values are shown as watts per a kilogram. This doesn’t yet support different weights over time, so old powers won’t be shown accurately if your weight has changed much.
For reference, here’s a handy table that Andrew Coggan put together showing what power outputs cyclists tend to be able to produce. You should probably also read Andrew Coggan’s explanation of the table.
