How this is calculated

Formula:

volume_target = volume_source

In plain language:

Volumes normalize to cubic meters, then render as gallons, quarts, pints, cups, or metric units using exact US customary factors.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Gallons to quarts explained

Labels on cleaners, broths, and parts washers often list capacity in gallons, while recipes and dosing guides ask for quarts. In US liquid units, $1\,\text{gal} = 4\,\text{qt} = 8\,\text{pt} = 16\,\text{cups}$ . The converter flips either way and keeps pints, cups, and liters beside the result.

How the conversion works

Inputs convert to cubic metres, then scale with exact US customary ratios.

$\text{quarts} = \text{gallons} \times 4$ $\text{gallons} = \text{quarts} \div 4$ $\text{liters} = \text{gallons} \times 3.785411784$

Units and conversions

Unit	Symbol	Relation
US gallon	gal	$1\,\text{gal} = 3.785411784\,\text{L}$
Quart (US)	qt	$1\,\text{qt} = 0.25\,\text{gal}$
Pint	pt	$1\,\text{pt} = 0.5\,\text{qt}$
Cup (US)	cup	$1\,\text{cup} = 0.25\,\text{qt}$

Worked examples

Stockpot fill
$5\,\text{gal} \times 4 = 20\,\text{qt}$ .
Packaging cleaner
$6\,\text{qt} \div 4 = 1.5\,\text{gal}$ .
Soup batch sizing
$10\,\text{qt} \times 2 = 20\,\text{pt}$ ; also $10 \times 4 = 40\,\text{cups}$ .

Tips and pitfalls

Use US liquid quarts; dry quarts (1.101 L) and imperial quarts (1.13652 L) are larger.
For mid-size batches, quarts avoid fractional gallons and oversized cup counts.
When collaborating with metric teams, convert to liters by multiplying gallons by 3.785411784.
