Feel free to test our converter between perceived weight on Earth and on Pluto, it converts automatically when you type in one of the fields. Here you can easily enter how much you weigh (on Earth) and find out how much it would feel like you weigh if you were on Pluto's surface.
In order to understand what the meaning is when one speaks about how much one "weighs" on Pluto, you first have to get familiar with the concepts of mass and weight. We have written a longer explanation about this on our subpage about how much one weighs on the moon, you can check it out here: How much do I weigh on the Moon? But the gist of it is that what we are talking about is perceived weight, not how much one actually "weigh" expressed in for example the SI unit for mass (which is kilograms).
