Wattage?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I'm curious how much wattage I would be producing when doing a climb, and riding flat. I'm 22 yrs old, 175lbs, riding about 10mph uphill at a 90 cadence (fairly steep hill), and riding 20mph on a flat with a 90 cadence.

I don't have access to a power meter, and I know there are a bunch of variables that go into the wattage readings...so please just give me a ballpark number.

Reason: I'm buying Kreitler rollers, and I am trying to figure out if how many accessories are necessary for me to buy to increase resistance.

"failry steep" is fairly vague... the actual slope will matter a lot.
on the flats hand position matters a lot.

You can get the elevations from google earth maps free software calculate the slope and plug in the numbers here http://www.analyticcycling.com/ForcesPower_Page.html
