>Problem with m3 is that it is HUGE for measuring fluids >in home and medical use.
In nearly all cases I agree. Although not always. My water bill is in m3. Tesla and Farads are also huge. However, I still think it is acceptable to use huge units in domestic applications. There are important issues here: 1. Transition from one system to another (as in the US, Canada, Ireland and UK) presents back-translation (and familiarity) problems that do not really exist once totally immersed. 2. Units of time (and combinations) present problems that do not exist with other units. 3. The universal nature of the SI system is the strength. The more it is used by ordinary people, the easier it gets. 4. People clearly do accept milli and micro as units. Having said all that, I am not sure what I would suggest for the water consumption scenario. -- Terry Simpson Human Factors Consultant [EMAIL PROTECTED] www.connected-systems.com Phone: +44 7850 511794
