Volume

5.28 US gal

High confidence

1 L = 0.264172 US gallons. Metric and US container sizes do not correspond — order by required volume, not by nearest tin size.

Conversion factor applied
0.26 US gal per L

Metric product sizes being checked against American coverage data need this direction, and the mismatch in container standards is the practical difficulty. A five litre tin is 1.32 US gallons and a ten litre is 2.64, so neither lines up with a quart, a gallon or a five-gallon pail. That means a coverage calculation done in one system cannot simply be met by buying the nearest-looking container in the other; the volume required has to be converted and then made up from whatever sizes the supplier actually stocks, usually with a surplus. A litre is about six percent larger than a US quart, which is close enough to mislead anyone treating the two as interchangeable.

Add the equipment this sizes

This result is a specification — 5.283 US gal — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why do metric tin sizes look odd in gallons?
Because the two systems standardised on different container sizes. A 5 litre tin is 1.32 US gallons and a 10 litre is 2.64, so neither maps onto a quart, gallon or five-gallon pail. Order by the volume you need rather than by container equivalence.
Is a litre about a quart?
Close — a US quart is 0.946 litres, so a litre is about six percent more. Useful for a rough mental check and not accurate enough to substitute one container for another on a materials order.
Does temperature affect liquid volume?
Slightly, and it is normally irrelevant for construction materials. It matters for fuel measurement and for large tank calibrations, where volumes are quoted at a reference temperature.
