You can use Unix or DOS proj (rel 4 from charon.er.usgs.gov 184.108.40.206).
A few notes.
Washington has two zones: 4601 for the northern half and
4601 for the southern half. Dividing line usually on a county line.
I have a list of counties and zones.
Which datum is being used: NAD27 or NAD83.
Washington is convered by two UTM zones: 10 for 126W-120W and
11 for 120W-114W
For data from the NW part of the state the following is an example
assuming input data in NAD27 SPCS coordinates:
proj -I +init=nad27:4601 -o <<EOF | proj -i +proj=utm +zone=10 +ellps=clrk66
496806.20 67808.27 somewhere in Seattle
488309.43 197730.10 somewhere in Bellingham
The results should look like:
If using NAD83, change +init=nad83:4601 and +ellps=GRS80. DO NOT mix
If there are any further questions, please contact me.
