Why this conversion matters in chemistry

Pharmacy formulary translation is a typical place to need it. A 1 L 0.9% NaCl IV bag is 1.057 US quarts on a legacy US drug-compendium reference, which is what you want when reconciling a European-pharmacopoeial spec against a US-formulary listing for hospital-system parenteral-nutrition harmonization. The multiplier of 1.05669 qt per L follows from the US quart definition (946.353 mL). The job is closing the gap between metric pharmaceutical specs and US-customary inventory documentation.

Formula

qt = L × 1.05669

Worked Examples

1 L = 1.057 qt

The conversion anchor — one liter is about 5.7% more than one US quart.

3.785 L = 4 qt

Exactly one US gallon — four quarts by the gallon definition.

0.946 L = 1 qt

Exactly one US quart — the reverse conversion anchor.

5 L = 5.283 qt

A 5 L reagent-bottle volume in US quarts.

Frequently Asked Questions

How do I convert liters to quarts?
Multiply by 1.05669. So 1 L becomes 1.057 US quarts. The factor is exact through the US quart definition of 946.353 mL.
Is 1 liter equal to 1 quart?
Approximately — 1 L = 1.057 US qt, about 5.7% more. For quick mental scaling the two are close enough; for careful work the exact factor matters.
How many liters in a gallon?
1 US gallon = 4 quarts = 3.78541 L. The chain links the gallon, quart, and liter cleanly through their respective definitions.
Why would a chemist convert liters to quarts?
Scaling lab processes for US manufacturing, working with US customary inventory documentation, or communicating with industries that haven't moved to metric. Professional chemistry stays in liters; the conversion lives at the cross-system boundary.
