Also to know is, what is the density of water in pounds per cubic foot?
One pint of water weighs one pound (1.04316 lbs/pint). One gallon of water weighs 8.3453 pounds. One cubic foot of water contains 7.48052 gallons. The weight of one cubic foot of water is 7.48052 gallons times 8.3453 pounds, which equals62.42718356 pounds of water per cubic foot.

Why is the density of water is 1?
Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.

What does a specific gravity of 1.020 mean?
To put it another way, the specific density of water would be 1.000. Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.

What is the unit weight of reinforced concrete?
In USCS units (United States Customary System units), its weight comes to ~150lb/ft^3 and ~2,400 kg/m^3 if measured in Metric SI system. The concrete calculator is calibrated to exactly 23.60 kN/m^3 unit weight per concrete volume. Which is defined as, how heavy is the normal reinforced concrete.

What is the density of water at room temperature?
In general, we say that the density of water is 1000 kg/m^3 (or 1 g/cm^3). But you're right that it does vary a little bit with temperature. It is exactly 1000 kg/m^3 at 4 degrees Celsius. At 20 degrees Celsius it is 998.23 kg/m^3 ( or 0.99823 g/cm^3).

What is the specific weight of water?
The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma). A commonly used value is the specific weight of water on Earth at 4°C which is 9.807 kN/m3 or 62.43 lbf/ft3.
6
What is the unit slug?
The slug is a derived unit of mass in the weight-based system of measures, most notably within the British Imperial measurement system and in the United States customary measures system. A slug is defined as the mass that is accelerated by 1 ft/s2 when a force of one pound (lbf) is exerted on it.

Why is it important to know the specific gravity?
4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid's characteristics compared to a standard, usually water, at a specified temperature.

What is specific gravity of urine?
Urinary specific gravity (SG) is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with water density and provides information on the kidney's ability to concentrate urine. A urinary specific gravity measurement is a routine part of urinalysis.
9
Is weight density?
The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.
10
Is density mass?
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.
11
What is the weight of water?
The US gallon, which is equal to approximately 3.785 L, is legally defined as 231 cubic inches. A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon.
12
What is the unit of weight?
The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
13
What is the density of water in kg L?
Many people still use g/cm3 (gram per cubic centimeter) or kg/L (kilograms per liter) to measure density. SI standard is kg/m3. 1 kg/dm3 = 1000 g/1000 cm3 = 1 kg/L. The correct SI unit of denstity of water is "ρ = 1000 kg/m3".
14
Is specific gravity and density the same?
Because the density of water is 1 g/cm3, it is the most widely used reference substance for determining the specific gravities of solids and liquids. The density of any substance in grams-per-cubic-centimeter is nearly the same numerically as its specific gravity relative to water.
15
What is the unit of specific gravity?
Specific gravity is a dimensionless quantity; that is, it is not expressed in units. To find the sp gr of a solid or liquid, you must know its density in kilograms per meter cubed (kg/m3) or in grams per centimeter cubed (g/cm3). Then, divide this density by the density of pure water in the same units.
16
What is the submerged unit weight?
Saturated unit weight is equal to the bulk density when the total voids is filled up with water. Buoyant unit weight or submerged unit weight is the effective mass per unit volume when the soil is submerged below standing water or below the ground water table.
17
What is the known density of water?
Pure water has a density of 0.99823 grams/cubic centimeter at 1 atm pressure and a temperature of 20 degrees Celsius (68 degrees Fahrenheit).
18
What is the definition of specific volume?
Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m. 3 · kg -1 ).
19
What is specific density?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. It is defined as a ratio of density of particular substance with that of water.
