This article gives a list of conversion factors for several physical quantities.A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit.
If a template uses {{Infobox person/weight|{{{weight}}}|kg-stlb=yes}}, then an article using that template with an input in kg will display two conversions: lb followed by st/lb (default is one conversion to lb):
Biomusicology is the study of music from a biological point of view. The term was coined by Nils L. Wallin in 1991 to encompass several branches of music psychology and musicology, including evolutionary musicology, neuromusicology, and comparative musicology.
Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology". [15] It establishes a common understanding of units, crucial to human activity. [2]
kg mass "The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the metre and the second are defined in terms of c and ∆ν Cs." [1]
In metrology (the science of measurement), a standard (or etalon) is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity. [1] Standards are the fundamental reference for a system of weights and measures , against which all other measuring devices are compared.

Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician , while someone working in the field of acoustical engineering may be called an acoustical engineer . [ 3 ]
