The amount of mass that can be lifted by hydrogen in air per unit volume at sea level, equal to the density difference between hydrogen and air, is: (1.292 - 0.090) kg/m 3 = 1.202 kg/m 3. and the buoyant force for one m 3 of hydrogen in air at sea level is: 1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N
One litre of liquid water has a mass of almost exactly one kilogram, due to the gram being defined in 1795 as one cubic centimetre of water at the temperature of melting ice. [4] The original decimetre length was 44.344 lignes, which was revised in 1798 to 44.3296 lignes. This made the original litre 1.000 974 of today's cubic decimetre. It was ...
The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [2] decreasing to 12–20 breaths per minute ...
On 7 April 1795, the metric system was formally defined in French law using six units. Three of these are related to volume: the stère (1 m 3) for volume of firewood; the litre (1 dm 3) for volumes of liquid; and the gramme, for mass—defined as the mass of one cubic centimetre of water at the temperature of melting ice.

At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3.
2 Kolve = 1 Chipte (about quarter litre) 2 Chipte = 1 Mapte (about half litre) 2 Mapte = 1 Ser (about one litre) Liquid Volume Measures. These were hour glass shaped measure used for Milk, Ghee, Oils. The bottom was round like an inverted dome, the top was like flared rim. This shape helped in pouring the liquids. 4 Chhataank = 1 Pav 4 Pav = 1 Seer
1 imperial bushel = 8 imperial gallons = 4 imperial pecks = 36.368 72 litres: ≈ 8.25645 US dry gallons ≈ 9.60760 US fluid gallons ≈ 2 219.36 cubic inches: ≈ 1.284 35 cubic feet 1 US bushel [6] = 8 US dry gallons = 4 US pecks = 2 150.42 cubic inches = 1.244 46 cubic feet = 35.239 070 166 88 litres ≈ 9.3092 US fluid gallons ≈ 7.7515 ...
Liquefied gas (sometimes referred to as liquid gas) is a gas that has been turned into a liquid by cooling or compressing it. Examples of liquefied gases include liquid air , liquefied natural gas , and liquefied petroleum gas .
