By a bit of guesstimation.
SIZ in BRP is explicitly a measure of mass (the author of BRP's predecessor RuneQuest slapped me down - politely - in a playtest forum and told me so straight)
One problem is that SIZ progression is non-linear (I confess I don't quite understand why but wiser people than I have said that otherwise it would just explode out all control) so any equation will be either fairly complex OR only valid for a small range of SIZ values.
The other is that density is going to have a BIG impact. For animals no doubt one COULD draw up a chart of SIZ - mass - estimated height/length. 'Simply' (hmmm) plugging in the length of a real world animal with a mass similar to that in the mass column.
