This is a SystemOfUnits implementation based on a Reddit article calculating the heights and weights of the Guardians Of The Galaxy and a JUnit test suite for each character.
We also added Fat Thor anticipating "Guardians of the Galaxy 3" where he might play a role again, based on Chris Hemsworth's height and estimated weight (220lb) plus the fat suit he was wearing in "Avengers Endgame". If you would like to calculate Fat Thor's BMI, please also check out UoM Health Demos ;-D
