How to convert smartphone batteries to foes
foe = smartphone battery × 5.4 × 10-40
To convert smartphone batteries to foes, multiply the number of smartphone batteries by 5.4 × 10-40 .
Example: 1 smartphone battery to foe
Start with the value in smartphone batteries: 1 smartphone battery.
Multiply by 5.4 × 10-40 : 1 × 5.4 × 10-40 = 5.4 × 10-40 .
Result: 1 smartphone battery = 5.4 × 10-40 foes .
Going the other way, 1 foe = 1.8518519 × 1039 smartphone batteries, so to convert foes back to smartphone batteries you divide by the same number. See foes to smartphone batteries .
