Calculate Liters in a Balloon
Calculator how many liters fit into a ball or balloon of a certain size and how big the content is at a certain fill level.
Mathematically, a balloon or ball is a sphere. There are other balloon shapes, but calculating those volumes is extremely complicated. The size of a perfectly round balloon is given by the radius or diameter, measured inside the balloon. Or you measure outside and subtract twice the wall thickness.
Example: a ball with a radius of 5 cm, i.e. a diameter of 10 cm, has a volume of 0.5236 liters.
Please enter any value, the other two values will be calculated.
If the balloon is only partially filled, then the volume has the shape of a spherical cap.
Example: a ball with a radius of 5 cm and a filling height of 8 cm has a volume of 469.1 milliliters.
Please enter the radius or diameter and the fill level, the other values will be calculated. The filling height must not exceed the diameter. If it is the diameter, then the balloon is full.
This balloon with a diameter of 16 centimeters holds more than two liters. If it is filled to ten centimeters, then it contains almost one and a half liters.
A sphere is a common shape for a ball or balloon, but not the only one. All shapes created by inflation are round in some way. The ball as a sporting device has a history that goes back thousands of years. Small, candle-powered hot air balloons have existed in China since the early third century. The first manned hot air balloon took flight in 1783. Rubber balloons came onto the market in the mid-19th century; before that, balloons made from goat bladders were sometimes used, and can still be seen today, albeit rarely, for traditional reasons.
