The values of the Btu and calorie are those of the International Table. Very large and very small numbers appear in e-Format and are not spaced. Unvalued zeros on all numbers have been suppressed. Caution NO guarantee as to the accuracy of these values is given. And they should be checked against some other source. A note on Format and Accuracy is available.
