Height and Weight Tweets are accepted as canon
However, since we know that BF is intentionally drawn smaller than it actually is, we won't be able to use the height in calculations. Because of this, we'll use the weight-only version of the calculation (using the low end, just like the original calculation):
- Girlfriend's Kinetic Energy:
147.37 Kilojoules (Wall level)
Low-End: 33,589.53*2 = 67,179.06 (Class 100)
High-End: 67,195.72 *2 = 134,391.44 (Class K)
That is, everyone becomes 9-B and Class 100
