Open toolConvert pressure, distance, and weight values instantly. Enter a value on either side of each pair and the matching unit updates automatically.
Convert tank rated volume (cuft) to water volume (liters) using working pressure.
This converter is independent from your saved unit preferences and does not require direction toggles.
Type in PSI or bar, feet or meters, pounds or kilograms, cubic feet tank rating or liters water volume (with working pressure), and Celsius or Fahrenheit. The paired value updates immediately.
1 bar = 14.5038 psi
1 meter = 3.28084 feet
1 kilogram = 2.20462 pounds
1 cubic foot = 28.3168 liters
Tank liters = (cuft * 28.3168) / pressure(bar)
F = (C * 9 / 5) + 32
