Pure water has its highest density

**1000 kg/m**or 1.940 slug/ft^{3}^{3}at temperature 4°C (=39.2°F).What is the real density of water?

The usual value used in calculations is 1 gram per milliliter (1 g/ml) or

**1 gram per cubic centimeter**(1 g/cm^{3}). While you can round the density to 1 gram per milliliter, here are more precise values for you. The density of pure water actually is somewhat ?less than 1 g/cm^{3}.11

## 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/s^{2}when a force of one pound (lbf) is exerted on it.13

## What is the weight of water per gallon?

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.14

## How much does a cubic meter of water weigh?

A cubic metre of pure water at the temperature of maximum density (3.98 °C or 39.16 °F) and standard atmospheric pressure (1013.25 kPa) has a mass of

**1000 kg**, or**one tonne**. At 0 °C (32 °F), the freezing point of water, a cubic metre of water has slightly less mass, 999.972 kilograms.15

## What is the density of water in kg m3?

ρ (rho) = density, m = mass, V = volume. The SI unit of density is kg/m

^{3}. Water of 4 °C is the reference ρ = 1000 kg/m^{3}= 1 kg/dm^{3}= 1 kg/l or**1 g/cm**= 1 g/ml.^{3}16

## What is the specific heat of water?

Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or

**4.184**Joules.17

## 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).18

## What is the unit of measurement for density?

The mass of water is expressed in grams (g) or kilograms (kg), and the volume is

**measured in**liters (L), cubic centimeters (cm^{3}), or milliliters (mL).**Density**is calculated by the dividing the mass by the volume, so that**density**is**measured**as units of mass/volume, often g/mL.19

## 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).
