because propane is a gas and at different temperatures or pressures it's density varies a lot in the same size container. Once pressurized, it will liquify. So to measure it fairly, it is measured by wieght.
A full 5-gallon propane tank typically weighs around 38-40 pounds, including the weight of the propane gas itself. However, the actual weight can vary slightly depending on the specific tank and manufacturer.
The difference is the bonds between the first pair of carbons. A Carbon atom requires 4 bonds in a molecule. In Propane, the three carbons have 1 bond between each of them, and the rest of their bonds are used for hydrogen, resulting in a C3H8 molecule. In Propene, the first 2 carbons will have a double bond, resulting in 2 less hydrogens in the molecule, C3H6. The difference between alkanes and alkenes are that a double bond is shared between a pair of the carbon atoms. In pro-2-ene, this would be the 2nd and 3rd carbon sharing a double bond. In just propene, it's the 1st and 2nd.
A typical example of a product sold by weight in grams is fresh produce like fruits and vegetables. It is common to purchase items like apples, bananas, and tomatoes by weight in grams to ensure accurate measurement and pricing.
Propane is commonly used by residential, commercial, and industrial customers for heating homes and buildings, cooking, hot water heating, and powering appliances such as dryers and stoves. It is also used in agriculture for crop drying, pest control, and heating greenhouses. Additionally, propane is used as a fuel source for vehicles like trucks and buses.
Varieties of LPG bought and sold include mixes that are primarily propane (C3H8), primarily butane (C4H10) and, most commonly, mixes including both propane and butane, depending on the season - in winter more propane, in summer more butane. So that people can smell the gas (for safety) chemicals that smell are added - ethanethiol, thiophene and amyl mercaptan.
KG is only used for liquified gas in cylinders such as propane which is sold by weight. Compressed gas and bulk liquid such as nitrogen is not sold by weight.
The unit of measure for propane fuel is typically expressed in gallons or liters for liquid propane. In terms of energy content, propane is often measured in British thermal units (BTUs) or megajoules (MJ). Additionally, propane is sometimes sold by weight, measured in pounds or kilograms.
Grain is usually sold by weight or mass. An appropriate measure of volume would be the liter, but it is rarely used. A few countries use bushels.Grain is usually sold by weight or mass.

The weight of my 1962 Volvo 544, originally sold in the UK with a 1.6 liter 4 cylinder engine, serial # 305XXX, is 2863 lbs. tkrumholz@gmail.com
I wasn't aware that there was more than one kind of liter. I though a liter was a liter was a liter.

Liquified propane sold as fuel in the US must be at least 90% pure propane; the rest is typically butane, propylene (5% maximum) and ethyl mercaptan, which is added to give it a noticeable and characteristic odor.
