	:<~~math~~>~~B_n = \frac{Wo}{P V F}~~ <~~/math~~>

	~~where~~:
	*'''B<sub>n</sub>''' is the Beale number
	*'''Wo''' is the power output of the engine ([[watt]]s)
	*'''P''' is the [[Arithmetic mean\|mean average]] gas [[pressure]] ([[Pascal (unit)\|Pa]]) or ([[MPa]], if volume is in [[centimeters\|cm<sup>3</sup>]])
	*'''V''' is swept [[volume]] of the power piston([[meters\|m<sup>3</sup>]]) or ([[centimeters\|cm<sup>3</sup>]], if pressure is in [[MPa]])
	*'''F''' is the engine cycle frequency ([[Hertz\|Hz]])

	~~==Estimating Stirling power==~~
	To estimate the power output of an engine, nominal values are assumed for the Beale number, pressure, swept volume and frequency, then the power is calculated as the product of these parameters, as follows:
