how to convert :-normal metre cube to meter cube.

metre and meter are the same thing.

[quote="Anonymous"]Representing "normal meter cubed" as Nm³ or nm³ is a bad practice, contrary to SI conventions because "n" is reserved as a prefix for nano-, and "N" is reserved for newton. This is guarenteed to cause confusion for some people who read it. Since "normal" is not usually used in the US, I don't know what the preferred notation is.

Not too sure that it is bad practice to use N for 'normal'. There are precendents for multiple use of the same letters, e.g. m for milli and metre. The key thing is to ensure that units are separated with spaces or full stops (e.g. N m or N.m for Newton metres) whereas prefixes are adjacent (e.g. Nm3 for normal metres cubed).

However, use of 'Normal' has always created confusion regarding what temperature is applied, e.g. 0 C, 15 C, 20 C, 60 F. I used to think it was 20 C but have now been converted to the 0 C definition (although this is anything but 'normal' where I live!). Perhaps the important thing is to ensure that the document/spec/data sheet that refers to Nm3 has a clear definition in terms of temperature. Don't thing there is any confusion on the pressure of 1.013 bar a though?

I dont think that Nm3 is a bad pratice as most of the design value of a gas flow mentioned by suppliers outside india is that.. only thing is we need to convert them to m3/h during calcutions - which is same as mentioned b4 - nm3 is volume at 1atm or 10330 mmWc and 273 K , and hence actual volume at given conditions can be evaluated by ideal gas law..

The SI Brochure (or NIST SP 330, if you're American) specifically deprecate attaching "qualifers" of any kind directly to the unit.
