WP 34S Unit conversion question

[rkf]

Thanks, Franz, for this clarification. But having a look at NIST Guide to SI units, one can see that all values are rounded to six decimal places, no matter if it makes sense or not. E.g.

kilometer per hour (km/h) into meter per second (m/s) 2.777 778 E-01

But thats clearly 2.7777777777... and not 2.7777780000. I doubt the kilogram per pound value was rounded the same way :-(
