convert varchar or char to float

Hello,
Is there a way to convert varchar or char to float?
Thank youSELECT Convert(float, '1e3')-PatP|||Thank you, what is '1e3' and how to apply it my field?|||1e3 is a float constant. I picked it because it can't be a decimal, money, or any other numeric value, either CHAR or FLOAT and that's it.

-PatP|||I have a field in my table "SellTo" datatype set to varchar

Thank you|||Just curious, but what are you really trying to do? You've posted several questions, all of which "miss the mark" in some important way. I think if you back off just a bit from the technical details and focus on the business task at hand and explain that for us, then we can probably give you much better (both easier to implement/understand and more useful) answers.
