RLO: SI Units

Glossary

• Joule: The SI  unit of work or energy. {Nm] (J)
• Kelvin: The SI unit of temperature. It is 1/273.16th of the thermodynamic temperature of the triple point of water.
• Litre: An SI derived nit of fluid volume. [0.001 cubic m] (l)
• Metre: The SI unit of the length. It is the distance light travels, in a vacuum, in 1/299792458th of a second. (m)
• Mole: The SI unit of amount of a substance. It is defined as the amount of substance that contains as many "particles" as there are atoms in 0.012 kg of carbon12. (Mol)
• Newton: The SI unit for forced [kgms-2] (N)
• Ohm: The SI unit for electrical resistance [V/A] (Ω)
• Osmole: The SI unit of osmotic pressure/tonicity of fluids. It is the osmotic pressure of a one molar solution of a substance that does not dissociate, in water. (Osm)
• Parameter: any factor that defines a system and determines(or limits) its performance.
• Pascal: The SI unit of pressure [N/m²] (Pa)
• Second: The SI unit of time. It is the length of time taken for 9192631770 periods of vibration of the caesium-133 atom to occur.
• Volt: The SI unit of the electrical potential [W/A] (V)
• Watt: The SI unit of work or energy flux [J/s]] (W)
• Weber: The SI unit for magnetic flux [V.s] (Wb)
