I believe that Convert.ToInt32(string) just checks for a null string (if the string is null it returns zero unlike the Parse) then just calls Int32.Parse(string). I’ll use the profiler to confirm this and to see if using Convert as opposed to Parse has trade range breakouts any real effect on performance. Convert.ToInt32 allows null value, it doesn’t throw any errorsInt.parse does not allow null value, it throws an ArgumentNullException error.
What’s the main difference between int.Parse() and Convert.ToInt32
Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. By contrast, psia measures pressure relative to a vacuum (such as that in space). Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure.

- The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre.
- This function will take a string and attempt to extract an integer out of it and then return the integer.
- Convert.ToInt32 allows null value, it doesn’t throw any errorsInt.parse does not allow null value, it throws an ArgumentNullException error.
- The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. The above form works if you are measuring differentialpressure, such as the difference in psi between two points.
Convert psig to bar – Conversion of Measurement Units
- It also gives the correct answer for absolute pressure,assuming you are measuring psia, which is the pressure relativeto absolute zero vacuum.
- If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi.
- TryParse is a new addition to the new .Net 2.0 framework that addresses some issues with the original Parse function.
- If it runs into something that it can’t parse then it throws a FormatException or if the number is too large an OverflowException.
- The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals).

The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). Its official symbol is “bar”; the earlier “b” is now deprecated, but still often seen especially as “mb” rather than the proper “mbar” for millibars.

Common speed conversions
This function will take a string and attempt to extract an integer out of it and then return the integer. If it runs into something that it can’t parse then it throws a FormatException or if the number is too large an OverflowException. For example, I just discovered today that it will convert a char directly to int using its ASCII value. The Convert class contains a series of functions to convert one base class into another.
The main difference is that exception handling is very slow, so if TryParse is unable to parse the string it does not throw an exception like Parse does. Instead, it returns a Boolean indicating if it was able to successfully parse a number. So you have to pass into TryParse both the string to be parsed and an Int32 out parameter to fill in. If you are measuring relative to vacuum and want to resolvethe pressure relative to the atmosphere, then you should usethe form below. Note that psig can measure differential pressure in someapplications and absolute pressure in others, so you needto know which one fits your calculation. The first of these functions, Parse, is one that should be familiar to any .Net developer.
