Temp (c): -20 / 19
Climb WT: 209.1 / 190.0
I think I more or less figured it out with the six step process below:
1. -20 – 19 = 39
2. 19 – 8 = 11
3. 11 / 39 = 0.28
4. 209,100 – 190,000 = 19100 lbs
5. 19,100 * 0.28 = 5,348
6. 5348 + 190.000 = 195,348
Its not exactly 195,000 pounds but its pretty close, which means I must be doing something right.
