To convert US liquid quarts to acre-feet, multiply the value by 7.67221 × 10⁻⁷. To go the other way, multiply acre-feet by 1,303,410 to get US liquid quarts.
| US Liquid Quarts (qt) | Acre-Feet (ac·ft) |
|---|---|
| 1 qt | 7.67221 × 10⁻⁷ ac·ft |
| 2 qt | 1.53444 × 10⁻⁶ ac·ft |
| 5 qt | 3.8361 × 10⁻⁶ ac·ft |
| 10 qt | 7.67221 × 10⁻⁶ ac·ft |
| 20 qt | 1.53444 × 10⁻⁵ ac·ft |
| 50 qt | 3.8361 × 10⁻⁵ ac·ft |
| 100 qt | 7.67221 × 10⁻⁵ ac·ft |
| 500 qt | 0.00038361 ac·ft |
| 1,000 qt | 0.000767221 ac·ft |
25 qt × 7.67221 × 10⁻⁷ = 1.91805 × 10⁻⁵ ac·ft
Try this example →250 qt × 7.67221 × 10⁻⁷ = 0.000191805 ac·ft
Try this example →US liquid quart (qt). A US liquid quart is a quarter of a gallon (946.35 mL).
Acre-foot (ac·ft). An acre-foot is the volume of water covering an acre to a depth of one foot (1,233.5 m³), the US water-resources unit.
There are 7.67221 × 10⁻⁷ acre-feet in one US liquid quart.
Multiply the number of US liquid quarts by 7.67221 × 10⁻⁷. For example, 10 US liquid quarts equal 7.67221 × 10⁻⁶ acre-feet.
One acre-foot equals 1,303,410 US liquid quarts.
