Euric, I think you're reading way too much into this. Someone has simply converted a rough number from metric to customary, and in keeping 2 digits implied an unjustifiably high precision. I wouldn't be surprised if 9� is also a conversion from 5� C. I'm just glad to see that someone at Honeywell was using the metric system.
