The result updates as you type, and the swap button flips the conversion to us gallon → milliliter without reloading.
The conversion uses the precise factor (gal = mL × 0.0002641720524), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
