Calculation based on existing column, don't know range

[RoccoM]

Need help with the following:
I have a height and width column in pixel count. I convert the pixels to inches without a problem.
How do I figure out the last row in the column. They amount of rows will change every time I pull my data. In other words, how can I create my calculation for each row, when I do not know how many rows my data will contain?

	A	B	C	D
1	Height in Pixels	Width in Pixels	Height in Inches	Width in Inches
2	400	200	=a2/40*1.75	=b2/40*175

6
etc...

Thanks for the help
Rocco

I think if you format it as a table, You can just use the formula to expand the range of the table so if your range keeps changing your formulas will account for it

Yeah, if you convert your range into a table with headers, if you enter the formula into Height in inches and the other one in height to formula, it will automatically calculate what you're trying to do for each row.

Thanks for the reply. It's a great option. I got impatient. Before I saw the responses to my post, I just put in code to count the rows in column A. (never blank rows in the data). Then I stored the result in a variable. Using the range command, I can successfully enter the range (variable). I got this from another post in this forum.

Thanks for the help! I will try to format as a table also. I like this idea!
