Why this conversion matters
Water storage, reservoirs, and irrigation reports use acre-feet; gallons make the quantity more tangible for household comparisons. The widget keeps the direction explicit so you can enter either side of the pair without doing the reciprocal by hand. It is built for quick checks where a calculator, specification sheet, recipe, map, or lab note uses the other unit.
For the default example, 1 acre-ft converts to 325851 US gal. Switching the direction shows the inverse relationship, so 325851 US gal converts back to 1 acre-ft with the same factor.
Formula and privacy note
The calculation uses 1 acre-ft = 325851 US gal. Forward conversion multiplies by that factor, and reverse conversion divides by it. Results are rounded to six significant figures for readable estimates, so very small scientific units and large planning units stay scannable. Check the unit labels before copying a result, especially when similar abbreviations appear in the same project. The reference table is generated from the same constant, and everything runs locally in your browser.
