gram thrust/oz thrust to watts

Is there a conversion table available to determine static thrust - grams/oz. to watts?

Purchased this 50mm fan which claims 580g static thrust and wondering what is the equivalent in watts?

Thanks.

How many cells are you running? Check your amp current draw.

As per recommendation by xflight.com, just a 2200 mah 3s lipo pack.

Hello Gerry
There is no chart or graph that would apply as all fans do not have the same performance. If some one like the manufacturer has done a chart for that exact fan maybe but that would be it. You can gather info from others and build a data base but unfortunately no 2 people test in the exact same manner so each set of data will not match.

This graph done by Klaus Scharnhorst back in 2006 will get you close.
Klaus was RCG's "winmodels" back then and if you do a search you will find quite a lot of info on EDF design and performance theory.
Just convert Newtons to grams or lbs......

Check your amp current and multiply it by your voltage, with above stock set up you get more likely 360Watts figure.

1000 watts for 23 N in 70mm.

I think around 1500 watts in.

Remember: the noted diameter is NOT fan diameter.....it is tail pipe exit diameter.
So the 1000watts/23N/70mm equates to FSA for maybe an 80mm EDF.
Static thrust from an 80mm at 100% FSA would be really close to 23N no?
