Description

This calculates the volume correction factor due to temperature according to ASTM-IP Table 54. This can be done using the computer algorithms used to develop the table or using the lookup table itself.

Options

Calculation Method

• From algorithm

Select this option to calculate temperature correction factor from the algorithms developed to create the table.

• From lookup table

Select this option to use the table values themselves. Any inputs which do not correspond to values in the table interpolation will be carried out to gain the temperature correction factor.

Precision

• Full
• Rounding

If rounding is selected the output is rounded to 4 decimal places as per the table otherwise values are displayed to full precision.
