NUCOS: Unit Converter for Spill Responders

Logo for NUCOS.

The NOAA Unit Converter for Oil Spills (NUCOS) is a simple desktop tool that converts basic units of velocity, mass, length, etc., but more specifically, converts units that are unique to oil spill response. NUCOS includes some of the lesser known units used in managing oil and chemical spills. For example, it converts the units for oil volume, viscosity, and density from the conversion list of the Dispersant Mission Planner 2, a tool that helps spill responders assess dispersant application system performance.

NUCOS is compatible with Windows XP and Vista, and Macintosh OS-X versions 10.4 and greater, Intel and PPC. Installation of NUCOS includes a short Help file.

NUCOS was developed by the Office of Response and Restoration (OR&R), National Ocean Service, NOAA. The current version, NUCOS 1.3, was webposted on October 2, 2009.
