Metric System tries to be as precise as possible. Earlier we said that 0 degrees centigrade = 273 K, now we say that 0 degrees celsius = 273.15 K and tomorrow an even precise unit will declare 0 degrees at 273.15323432 K.
For a layman its enough if we say that 0 degrees celsius = 273 K and the decimals matter only for a person studying/working with science. In the same way, 1 day contains 86,400 seconds and earth's circumference is 40,000 km. So milliseconds and decimal part of km are not relevant for a common man unless they ask for it. Lets talk at integer level for a layman and decimal level for a scientist or research guy. Madan __________________________________________________ Do You Yahoo!? Try FREE Yahoo!
