Hi Carol - I just pulled out my basal thermometer. The basal thermometer only has temperatures listed from 96 to 100 degrees, inclusive, and is very clearly marked to the tenths (in between each whole number). It's very easy to read the temperature to the tenths, like 96.7, and if you want to be daring (like Laura says), you could possibly estimate and say 96.78. I can't find my regular thermometer right now, but from what I remember I think that a regular thermometer's temperature range is a little higher (goes up to 106, maybe?), also in increments to the tenths. But a basal thermometer is so clearly marked that you can read to the tenths more easily. Hope that this helps.
Hugs to you all,
