Quick Estimation

For mental math, multiply cubic feet by 28:

1 ft³ × 28 = 28 liters (actual: 28.32)
10 ft³ × 28 = 280 liters (actual: 283)

Aquarium Sizing

When setting up an aquarium, volume determines fish capacity and equipment needs:

1 ft³ ≈ 28 liters ≈ 7.5 gallons
A 55-gallon tank ≈ 7.4 ft³ ≈ 208 liters

Calculating Room Volumes

To find room volume in cubic feet: length × width × height (all in feet). Then convert to liters if needed for comparison with metric specifications.
