One cord is exactly 72,491,127.28 drops, so converting cords to drops is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
A stack of firewood four by four by eight feet — 128 cubic feet. The metric drop, standardised at 0.05 millilitres, or twenty drops to the millilitre.
US and imperial measures share names and do not share sizes. The imperial gallon is 4.546 L against the US 3.785 L, and the imperial pint is 568 mL against 473 mL. A recipe or fuel figure is 20% out if the wrong gallon is used, so check which side of the Atlantic the number came from. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into drops, which is usually more useful than the bare number.
