The density of water is about 1 g/cm 3, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 ☌ (39 ☏). It is equivalent to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). It is defined by dividing the CGS unit of mass, the gram, by the CGS unit of volume, the cubic centimetre. View all measurement unit conversion calculators on the same page (may not work with all browsers requires Iframe).The gram per cubic centimetre is a unit of density in the CGS system, and is commonly used in chemistry. The calculators require that your browser has java script enabled. SI units to the indicated units, multiply by the indicated value. Values lower than 0.001 will be displayed in the e-format e.g. Temperature Online calculator, figures and tables showing heat of vaporization of water, at temperatures from 0 - 370 ☌. Figures and tables showing the enthalpy and entropy of liquid water as function of temperature - SI and Imperial Units. Values of 10 000 or greater will be displayed in the e-format e.g. Water - Density, Specific Weight and Thermal Expansion Coefficients. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). The density of water at Standard Temperature and Pressure (STP) is 62. The Density of Water at STP is used as a reference substance for defining the Specific Gravity of many things (e.g. For pure water, the density is 1 gm/cm 3 or 1000 kg/m 3. Density Water at STP (SI) The Density of Water as STP (Standard Temperature and Pressure) is 998.2071kg/m 3. All results shown will be equivalent values. Density of water is the ratio of the mass and volume of the water at room temperature is 998.2 kg/m 3.The density of any substance is defined as the amount of mass present in the unit volume of the given substance. To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. The density of water (H 2 O) changes depending on temperature and pressure - as with other substances. For example, the specific gravity of water at 4 oC is 1.0 while its density is 1.0 gcm -3.ĬONVERSION CALCULATORS Convert between Different Units of Measurement Index of Unit Converters Thus the basic mass unit, the kilogram, was first devised to be the mass of 1000 mL of water, which has a volume of 1000cm3. The metric system was originally devised so that water would have a density of 1g / cm3, equivalent to 103kg / m3. Because specific gravity is a ratio, it is a unitless quantity. The SI unit of density is kg / m3, representative values are given in Table 11.2.1. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 oC. Sorry, your browser does not support JavaScript, which is needed to run this calculator Density, Specific Gravity Definition:ĭensity and specific gravity have very similar, but not quite identical definitions.ĭensity is the mass of material per unit volume. The density of water is 1.940 sl/ft at 39 ☏ (4 ☌), and the specific weight in Imperial units is. The density of a fluid when changing both temperature and pressure can be expressed combining (4b) and (6b) : 1 1(from eq. Note: conversions are only valid under the same conditions of temperature and pressure. Density of a fluid changing both Temperature and Pressure. DENSITY UNIT CONVERSION CALCULATOR DENSITY UNIT Generally, the density of water (which is approximately about 1 gram/cubic centimetre) is taken as the standard value for calculating the density of substances.
