Leaving some tolerance for the weight of the balloon and the string, we can approximate that every liter of helium has a lifting force of one gram. A member of the rare gas chemical family, it is 1/7 as heavy as air. HELIUM & WEIGHT CHART The water volume specification available for DOT cylinders is usually cubic inches or liters, so start DOT calculations by converting the water volume in to cubic feet. Helium is a colorless, odorless and tasteless inert gas which has no toxic properties. The conversion factor from cubic feet to liters is 28.3168467117, which means that 1 cubic foot is equal to 28.3168467117 liters: 1 ft3 = 28.3168467117 L. To convert 43.2 cubic feet into liters we have to multiply 43.2 by the conversion factor in order to get the volume amount from cubic feet to liters. A liter, or litre, is a unit of volume in the metric system. ft. under the same conditions. A liter is defined as the volume of a … ft. of gas while the same cylinder of pure air may contain 144 cu. For example, an AL cylinder of pure helium may contain 134 cu. Liquid Helium at -452ºF is the coldest liquefied gas. Please rethink your helium balloon purchase. ft. Average Float Time 18 - 24 Hours + Ultra Hi-Float™ 1 - 4 Weeks High altitude products vary by elevation and weather conditions. It was built, and is maintained, by the Pacific Northwest National Laboratory with funding from the DOE Office of Energy Efficiency and Renewable Energy's Hydrogen and Fuel Cell Technologies Office. 60 Liters = 2.1188800 Cubic Feet (rounded to 8 digits) Display result as. Whether you’re an expert retailer, a professional buyer, or a parent planning for a party, the sheer number of options for helium cylinders and balloons can quickly get confusing if you don’t have a calculator and pen next to you.
