 Tetens is much more accurate over the range from 0 to 50 °C and very competitive at 75 °C, but Antoine's is superior at 75 °C and above.The unattributed formula must have zero error at around 26 °C, but is of very poor accuracy outside a very narrow range.Tetens' equations are generally much more accurate and arguably simpler for use at everyday temperatures (e.g., in meteorology).
