I am converting a string like "41.00027357629127", and I am using;
Convert.ToSingle("41.00027357629127");
or
float.Parse("41.00027357629127");
These methods return 4.10002732E+15.
When I convert to float I want "41.00027357629127". This string should be the same...

First, it is just a presentation of the float
number you see in the debugger. The real value is approximately exact (as much as it's possible).
Note: Use always CultureInfo information when dealing with floating point numbers versus strings.
float.Parse("41.00027357629127",
System.Globalization.CultureInfo.InvariantCulture);
This is just an example; choose an appropriate culture for your case.
The precision of float is 7 digits. If you want to keep the whole lot, you need to use the double type that keeps 15-16 digits. Regarding formatting, look at a post about formatting doubles. And you need to worry about decimal separators in C#.
You can use the following:
float asd = (float) Convert.ToDouble("41.00027357629127");
You can double.Parse("41.00027357629127");
Use Convert.ToDouble("41.00027357629127");
You can use parsing with double instead of float to get more precision value.
