Ok, I think I found solution. Please, anyone confirm me that is ok?

Private Sub Command1_Click() a = Text1.Text b = ((a + 0.55) / Sqr(2)) ^ 2 / 50 Text2.Text = b End Sub

What happens you when you put a value in? Do you get the expected results?

Problem is that I do not know what results must be.

This formula is to get mWatts from radio transmitter antenna, readed with RF probe sonde and measured with Digital Volt Meter that give result in mV.

I have try to measure one transmitter, and on the end I have on my Digital Volt Meter value of 100 mV, and this math calculation give me 101 mWatts (that is I think near real measurement).

Sorry for my English.

Okay.. step back and just look at the forumula. If you pump a few different values in there - by and - and then in your code snippet do they appear to be the same?

No, then value is not the same, when I do this.
