How do you pronounce this greek letter?

The enthalpy of combustion, or the enthalpy of formation have deltaH symbols,

deltaHf and deltaHc, and in each case there's a little circle with a horizontal line through it, as a superscript.

It stands for the standard conditions, but how do you say it?

Update:

No, it's not theta, because it really is a circle, not a zero or oval., and the horizontal line extends beyond the circle. It's about double the diameter of the circle.

The one place I've seen something like it before is the plumb line on a ship

    Y, I, H are all pronounced as "I" (as in kit, BIT, etc). The small letter (lessen case) for "Y" (YPSILON) is "u" (or "υ" in Greek). "M" is pronounced exactly the equal because the english "M". The letters are Epsilon (the "E" as in Helen), Ypsilon (the "Y") and Iota (the "I"). I hope this helps!
