| Character's Appearance | Character's Name | Earth Weight | Photonis Weight | Mass |
|---|---|---|---|---|
| Susan | 105 lbs. | 35 lbs. | 47.727272 kg. |
| Sally | 130 lbs. | 43.3333333 lbs. | 59.090909 kg. |
| Candy | 125 lbs. | 41.6666667 lbs. | 56.818182 kg. |
| Goldilocks | 118 lbs. | 39.3333333 lbs. | 53.636363 kg. |
| Alice | 110 lbs. | 36.6666667 lbs. | 50 kg. |
| Michelle | 140 lbs. | 46.6666667 lbs. | 63.636363 kg. |
| Dottie | 150 lbs. | 50 lbs. | 68.1818182 kg. |
| Patience | 123 lbs. | 41 lbs. | 55.909091 kg. |
| Penny | 90 lbs. | 30 lbs. | 40.909091 kg. |
You could also solve for a character's weight on Photonis by dividing her Earth weight by 3. If you already know the Photonis weight but not the Earth weight, then multiply by 3. Susan & Penny's given weight info was a clue to that! (90 ÷ 30 = 105 ÷ 35 = 3)
What the weight-to-mass ratio of gravity means is that there is a certain amount of weight for each unit of mass. In this case, there's a certain number of pounds for each number of kilograms. Rephrasing what was typed on the puzzle page, there are 11 pounds for every 5 kilograms on the planet Earth; there are 11 pounds for every 15 kilograms on the planet Photonis.
