Hi John M. Steele, John Altounji, Michael Payne, Thank you for all the answers. Looked at the articles similar to articles written in soil journal a few years ago in the USA. I know in engineering notation numbers expressed in powers of 10^3-9 is common but not in life sciences. For acre-feet I have seen cubic meters and some dekameter references. Gives me an idea range of use.
