Using this formula for a variety of common glow motor sizes gives the following results:

.049 or .051 = 100 watts

0.10 = 200 watts

0.15 = 300 watts

0.25 = 500 watts

0.32 = 640 watts

0.40 = 800 watts

0.45 = 900 watts

0.51 = 1020 watts

0.61 = 1220 watts

0.75 = 1500 watts

0.91 = 1820 watts

idea to discuss what would be the most appropriate
