Note: I do not know the definition of
"intlTableBTU" within the phrase
"International Table BTU".  The following
sound alike: intl ampere, intl foot, intl
mile, intl yard.  The following partially
match: intensity of force, interfacial
tension, induced emf, inductance, inch, in,
in H2O, inch of water, inches of water, inhg,
inch of mercury, inches of mercury.
