At least the NSF likes metric

The Metric Conversion Act of 1975, as amended, and Executive 
Order 12770 of 1991 encourage Federal agencies to use the 
Metric System (SI) in procurement, grants and other business
related activities. Proposers are encouraged to use the Metric 
System of weights and measures in proposals submitted to the 
Foundation. Grantees also are encouraged to use metric units 
in reports, publications and correspondence relating to 
proposals and awards. 

I am still waiting for road signs...
