I'm looking for a gravity calculator...

I need a calculator
in the same style as a stardate converter

that looks sorta like...

Earth Rotation speed in hours(Reset:1.0/24)____

Human weight____

Understand? (<<<Not to be demanding, I had trouble writing that.)

The mass and diameter of the planet are much more important than the rotational speed of the planet; I suspect that any Earth-like world ould not have a fast enough rotation to effect a noticable change in the the weight of a person on the equator.
At the equator on Earth, your weight is reduced by 0.3% compared to your weight at the poles;
if the Earth span ten times as fast your weight would be reduced by perhaps 3% (without taking into account the effects of the oblate nature of such a fast-spinning world).

I don't think most people would notice a 3% drop in their weight- you probably fluctuate that much over a day or two anyway, depending on diet and fluid intake.

I know!
I found out 6 hours after posting!

Thanks anyway!
