Incidentally, 2 US pints would have a mass of almost 1 kilogram (actually 0.94636 kg), by virtue of approximating 1 litre: "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. Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact by definition." https://en.wikipedia.org/wiki/Litre Show
"L =US pt lqd / 2.1134" http://www.metric-conversions.org/volume/us-liquid-pints-to-liters.htmThe SI weight (a force) would be expressed in Newtons (N), found by multiplying the mass (in kg) by the acceleration of Earth's gravity (9.8 m/s/s) -see http://theory.uwinnipeg.ca/mod_tech/node25.htmlThus one US pint of water has a mass of 0.47318 kg, and weighs 9.8 x 0.47318 = 4.637164 N (or 1.04 pounds). An Imperial pint is a bit larger, equivalent to 1.2 US pints, giving it a mass of 0.567816 kg and a weight of 5.5645968 N (or 1.25 pounds). Latest update: August 31, 2022.

A list of most-searched-for questions and answers is included. There is also a specific section relating to the calculating of the size/volume/weight of home water heaters.
Be advised that this page is US-centric. As an example, this does not work in the UK where a pint is 1.25 pounds as opposed to US 1.043 pounds at room temperature (RT). There are also issues of temperature and density, both of which are addressed further down the page. The purpose of this page is for practical, everyday business-of-living uses only. For that it will serve you well. First – The Quick Answers to Volume Amounts and RatiosVolume Definitions

WALMART Summer Savings!See the latest deals.Converting Volume to WeightConverting volume to weight has everything to do with the density of the liquid. Fortunately, this question usually has to do with:
The rule of thumb, and the expression to remember is: "A pint's a pound the world around." The resulting estimates and extrapolations from this rule will serve you well for most everyday purposes. For scientific and industrial purposes where greater accuracy is required, a pint weighs a little bit more than a pound (1.043 lb.). Basic Formulas
This pretty much answers the question. Here are some other typical examples: Some Household Examples
Some gallon examples
The Density of the Liquid Significantly Affects the Rules Concerning Volume Conversion Calculations to WeightA major component of converting fluid volume to a weight measurement is the density of the fluid. For gasoline, water, and most grocery items; the rule of a-pint's-a-pound will serve you just fine. However, as an example, the rule probably wouldn't work too well with any significant volume of engine oil. As an extreme example, the liquid metal/element mercury would totally throw the pint's-a-pound rule out the window. So of course would any molten metal or alloy. Fluid density is also affected by temperature. This is why many people fill their gas tank first thing in the morning. There is more gas per gallon at 50 degrees Fahrenheit than at 90 degrees Fahrenheit. It should be noted the percentage difference is in the low single-digits. Here is a worthwhile page from NASA about Density, Mass (weight), Volume for both solids and liquids. List of Frequent Volume-to-Weight Conversion Q&AThe Most-Searched-for Questions and Answers for How Many Pounds
For folks who are interested, here is a beginner's Algebra Tutorial. This tutorial is specifically designed for people who are perfectly smart enough to learn algebra, but have a mental block that makes them think they can't. More Water and Gasoline Volume-to-Weight ExamplesDepending on what unit of measurement you use, volume will equal cubic English or cubic Metric; examples being cubic inches or cubic centimeters. Side note: the tilde (~) is the mathematical symbol for approximate. English
MetricMost of the world uses metric. There is a reason for that. As an example, 1000 cubic centimeters equals one liter, 1000 grams equals one kilogram, etc.; all nice, neat, and tidy. The United States and others are trying to get with the program; metric is already included with English measurement on most U.S. consumer items. It's only a matter of time. How Much Does the Water Weigh in a Full Water Heater?– Water Tank Size Volume Formula and Answers –
How to Calculate the Weight of the Water in a Home Water HeaterHow much does the total amount of water in a water heater weigh, volume to weight conversion. From the above NASA chart we see the volume formula for a cylinder is V = (πd2h)/4. Water tank heaters come in all sizes. For the purposes of this example, we will say the water tank heater has a measured height of approximately 54 inches; what with this, that, and the other, the water part is probably around 48". The diameter measured as 18"; what with insulation, etc., 16 probably works. So, Thus (" * " meaning to multiply), Since all numbers are inches, the answer will be in cubic inches. We reduce the formula as follows:
231 cubic inches is
equal to a gallon, so we divide 9646 by 231. What with the inner measurements being estimates, looks like it is a 40 gallon water heater.
Knowing the volume and weight of a 40-gallon water tank heater makes it easy to extrapolate the volume and approximate weight of other water heaters. Do remember that as volume increases, the discrepancy totals of the "pints-a pound". designation versus the more accurate 1.043 lb. designation also increases. As an example: multiplying the 320 lb. calculation for a 40 gallon water heater by 1.043 gives a result of 333.76 lb. at RT versus the original approximation of 320 lb. at RT. When the water temperature is at hot water heater level, the actual weight will fall between the 320 lb. calculation and the 333.76 lb. calculation.
Do keep in mind the temperature versus density considerations and the expansion of water when heated, i.e., a fully hot water heater tank weighs slightly less than a cold or warm water tank heater that's been freshly refilled after usage. The difference between hot and cold water density versus volume is significant enough that most water heaters have a temperature pressure relief valve and a drainage tube or pipe to compensate for this.

With the pint-equals-pound rule, one cubic foot of water weighs 60 pounds for approximation purposes.A cubic foot is 12 inches times 12 inches times 12 inches. So 1728 cubic inches equals 1 cubic foot. To convert cubic inches to cubic feet, simply divide the cubic inches by 1728. So using the above examples, we would have:
* A side note. I happened to stumble across this on Wikipedia: "Pound (mass), a unit of mass often abbreviated incorrectly as 'lbs' in the plural. Abbreviations of units of measure do not use an 's' on the end for plural." May all your calculations be prosperous ones. - End of Article - Re: Using Mobile?
