The following equation gives the volume accurate to about 1 part in 70,000, equivalent to 0.1 °C:
V(ml./gr.) = 0.073554 + 0.000013245 * T + 1.22823*10-9 * T2
The volume (or density) versus temperature is something many of us use daily since it is the basis of mercury thermometry. You will note that the volume equation is nearly linear, as is usually assumed in Hg thermometer calibration.
