2.2 ACI Standards:
1.5 The values stated in either SI units or inch-pound units
211.1-91 (Reapproved 2009) Standard Practice for Selecting
are to be regarded separately as standard. The values stated in

each system may not be exact equivalents; therefore, each
system shall be used independently of the other. Combining

values from the two systems may result in non-conformance
3.1 Defintions:
with the standard. Some values have only SI units because
inch-pound equivalents are not used in practice.
