How many liters are in one of each volume unit
Show the numbers
| Unit | Liters |
|---|---|
| Cubic inch | 0.016 L |
| Liter | 1 L |
| US gallon | 3.785 L |
| Imperial gallon | 4.546 L |
| Cubic foot | 28.317 L |
Converting area and volume units
Area and volume are where unit conversion most often goes wrong, because the length factor gets squared or cubed. One meter is 3.28 feet, but one square meter is 10.76 square feet and one cubic meter is 35.31 cubic feet. Every unit here is defined by an exact factor to a base unit — square meters for area, liters for volume — and your value goes into the base and back out:
result = value × factor(from) ÷ factor(to)
Why you cannot reuse the length factor
| Dimension | Meters → feet | Factor |
|---|---|---|
| Length | 1 m = 3.281 ft | 3.281 |
| Area | 1 m² = 10.764 ft² | 3.281² |
| Volume | 1 m³ = 35.315 ft³ | 3.281³ |
The classic mistake is multiplying 10 m² by 3.28 and getting 32.8 ft². The real answer is 107.6 ft² — more than three times larger. A square 1 m on a side is 3.28 ft on each side, so its area is 3.28 × 3.28. The same logic cubes the factor for volume.
Common area conversions
| From | To | Exact factor | Example |
|---|---|---|---|
| Square feet | Square meters | × 0.09290304 | 1,000 ft² = 92.9 m² |
| Square meters | Square feet | × 10.7639 | 50 m² = 538.2 ft² |
| Acres | Square feet | × 43,560 | Exactly, by definition |
| Acres | Hectares | × 0.404686 | 10 acres = 4.05 ha |
| Hectares | Acres | × 2.47105 | 1 ha = 2.47 acres |
A 12 × 15 ft room is 180 ft², which is 16.7 m². Flooring, paint, and turf are all priced by area, so convert the room's area — not its two side lengths separately — before comparing a metric quote with an imperial one.
Common volume conversions
| From | To | Exact factor | Example |
|---|---|---|---|
| US gallons | Liters | × 3.785411784 | 3 gal = 11.36 L |
| Liters | US gallons | × 0.264172 | 20 L = 5.28 gal |
| Cubic feet | Liters | × 28.3168 | 10 ft³ = 283.2 L |
| Cubic feet | US gallons | × 7.48052 | 10 ft³ = 74.8 gal |
| Cubic meters | Liters | × 1,000 | Exactly |
| Cubic inches | Milliliters | × 16.387064 | 231 in³ = 1 US gallon |
Volume conversions are usually the second half of a measurement. A pool 20 ft long, 10 ft wide, and 5 ft deep holds 1,000 ft³ — about 7,481 US gallons or 28,317 liters. To get from dimensions to a volume first, use the volume calculator; for floor plans and plots, the area calculator.
US vs. imperial gallons
A US gallon is 3.785 liters; a UK (imperial) gallon is 4.546 liters — about 20% larger. This converter uses the US gallon. If a figure comes from the UK, Ireland, or older Canadian sources, multiply imperial gallons by 4.54609 to get liters before converting further.
The converter also handles length, weight, and temperature in the same box. For those, the dedicated length converter, weight converter, and temperature converter show more units and worked tables.
Area & Volume Converter — frequently asked questions
How many square feet are in a square meter?
10.764. One meter is 3.2808 feet, and area squares the factor: 3.2808 × 3.2808 = 10.764. Multiplying square meters by 3.28 is the most common area conversion mistake.
How many gallons are in a cubic foot?
7.48 US gallons, or 28.32 liters. A space 20 ft × 10 ft × 5 ft holds 1,000 cubic feet, which is about 7,481 US gallons.
How do I convert acres to hectares?
Multiply acres by 0.404686. One hectare is 2.471 acres, and one acre is exactly 43,560 square feet.
Which units are supported?
Area: square centimeters, meters, kilometers, feet, yards, acres, and hectares. Volume: milliliters, liters, cubic meters, cubic inches, cubic feet, and US gallons. Length, weight, and temperature are also available in the same tool.
Can I control how many decimals are shown?
Yes. The precision field sets the number of decimal places in the result, from whole numbers up to fine precision for scientific use.
Why is temperature converted differently?
Temperature scales have different zero points, not just different step sizes, so conversion needs offset formulas — for example °F = °C × 9/5 + 32 — instead of a simple multiplication factor.
