From 1/8 to 1/2. That's the bad side of sensors; they're not very accurate. But very consistent when you know how they work. Use Bob's method described below.

That's the way to do it . No need to wait 'a few days'; just 'reset' the sensor (car idling, level surface) when the engine has been running fully hot (temp needle in/near the middle) for about 10 miles, and it'd be fully repeatable.
