But I think the width of the needle of our gauge will compensate for that.
It's an old style gauge with only a dot at 200F and the next dot is at 400F.
The best we can do is try to keep the needle below the 400F dot a tad. I
guess we could also calibrate it with a pan of oil, a hot plate, and a candy
thermometer.

If you're at sea level. If your elevation is substantially different from
that,
you need to look up the boiling point of water.
