This is roughly the sound of a mosquito flying 3 metres away. This is often abbreviated to just "dB"; however the correct abbreviation is dB(SPL), indicating decibel for Sound Pressure Level. 2P false Kilobyte A unit of information equal to 10³ (1000) bytes. 2Q false Kilo Becquerel kBq is 10³ Bq 2X false Metre Per Minute Metre Per Minute 4G false Microlitre A microlitre is one millionth of a litre 4H false Micrometre A micrometre is one millionth of a metre, also termed Micron. 4L false Megabyte A unit of information equal to 10 (1000000) bytes. 4N false Megabecquerel Megabecquerel: 106 Bq1 Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. 58 false Net kilogram A unit of mass defining the total number of kilograms after deductions. 59 false Part per million A unit of proportion equal to 10-6 (ppm). 5B false Batch A unit of count defining the number of batches (batch: quantity of material produced in one operation or number of animals or persons coming at once). 64 false Pound per square inch - Gauge Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig, on Earth, on a tire gauge represents an absolute pressure of 44.7 psi (lb/in²). 80 false Pound per square inch - Absolute Psia (pound-force per square inch absolute)is a unit of pressure pressure relative to a vacuum (such as that in space). At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig, on Earth, on a tire gauge represents an absolute pressure of 44.7 psi (lb/in²). /L false per litre (/L) Per Litre [/L] (Unified code) /mL false per millilitre (/mL) Per millilitre [/mL] (Unified Code) /mmol false per millimole (/mmol) Per millimole [/mmol] (Unified code) [APL'U] false IgA phospholipid units [APL'U] IgA phospholipid units - biologic activity of anticardiolipin [APL'U] (Unified code) [beth'U] false Bethesda unit [beth'U] Bethesda unit - biologic activity of factor VIII inhibitor [beth'U] (Unified Code) [GPL'U] false IgG phospholipid units [GPL'U] IgG phospholipid units - biologic activity of anticardiolipin IgG [GPL'U] (Unified Code) [HPF] false per high power field [HPF] Per high power field - view area in microscope [/[HPF]] (Unified Code) [lb_av]/[ft_i]3 false Pound per cubic foot Pound per cubic foot, [lb_av]/[ft_i]3 (Unified Code) [lb_av]/[in_i]3 false Pound per cubic inch Pound per cubic inch, [lb_av]/[in_i]3 (Unified Code) [iU]/d false International unit per day [iU/d] International unit per day [iU/d] (Unified Code) [iU]/L false International unit per litre [iU/L] International unit per litre [iU/L] (Unified Code) [iU]/mL false International unit per millilitre [iU/mL] International unit per millilitre [iU/mL] (Unified Code) [LPF] false Per low power field [LPF] Per low power field - view area in microscope [/[LPF]] (Unified Code) [MPL'U]/L false IgM phospholipid units [MPL'U] per litre IgM phospholipid units - biologic activity of anticardiolipin IgM – MPL unit per litre [[MPL'U]/L] (Unified code) A11 false Angstrom A unit of length equal to one hundred-millionth of a centimetre, 10–10 metre, used mainly to express wavelengths and interatomic distances.

BP false Hundred board foot A unit of volume equal to one hundred board foot. BPM false Beats Per Minute Beats Per Minute BQL false Becquerel The becquerel (symbol Bq) is the SI derived unit of radioactivity. One Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. SI uses the becquerel rather than the second for the unit of activity measure to avoid dangerous mistakes: a measurement in becquerels is proportional to activity, and thus a more dangerous source of radiation gives a higher reading. A measurement in seconds is inversely proportional. BTU false British thermal unit The British thermal unit (BTU or Btu) is a traditional unit of energy. It is approximately the amount of energy needed to heat one pound of water one degree Fahrenheit. One Btu is equal to about 1.06 kilojoules. It is used in the power, steam generation, heating and air conditioning industries.

C34 false Mole The mole (symbol mol) is the SI base unit of amount of substance; one of a few units used to measure this physical quantity. A mole will possess mass exactly equal to the substance's molecular or atomic weight in grams. That is to say, a substance's atomic or molecular mass in atomic mass units is the same as its molar mass in grams. Because of this, one can measure the number of moles in a pure substance by weighing it and comparing the result to its molecular or atomic weight C45 false Nanometre Nanometre- a billionth of a metre (10 to the negative 9th power) C47 false Nano Seconds A nanosecond is an SI unit of time equal to one thousand-millionth of a second (or one billionth of a second), that is, 10−9 seconds.

D40 false Thousand Litre References SI system of units of measure D43 false Atomic Mass Units (AMU) Atomic Mass Units D53 false Watt per metre Kelvin Specifies the thermal conductivity (lambda value): a measure of the product's ability to conduct heat. D5 false Kilogram per square centimetre A kilogram-force per square centimeter (kgf/cm2), often just kilogram per square centimeter (kg/cm2), or kilopond per square centimeter is a unit of pressure using metric units. Its use is now deprecated; it is not a part of the International System of Units (SI), the modern metric system. The unit is similar to the English unit psi (lbf/in2).

DRA false Dram (US) The dram (archaic spelling drachm) was historically both a coin and a weight. Currently it is both a small mass in the Apothecaries' system of weights and a small unit of volume. This unit is called more correctly fluid dram or in contraction also fluidram. The term also refers to the fluid dram, a measure of capacity equal 1⁄8 of a fluid ounce, which means it is exactly equal to 3.696 691 195 312 5 mL in the United States. DRI false Dram (UK) The dram (archaic spelling drachm) was historically both a coin and a weight. Currently it is both a small mass in the Apothecaries' system of weights and a small unit of volume. This unit is called more correctly fluid dram or in contraction also fluidram. The fluid dram is defined as 1⁄8 of a fluid ounce, which means it is exactly equal to 3.551 632 812 500 0 mL in the Commonwealth and Ireland. In England dram came to mean a small draught of cordial or alcohol; hence the term dram-house for the taverns where one could purchase a dram.

This quantity is commonly called grammage both in English and French (ISO 536), though many English-speaking countries still refer to the "weight". The term density here is used somewhat incorrectly, as density is mass by volume. More precisely, it is a measure of the area density, areal density, or surface density. Gram per kvadratmeter: I det metriska systemet uttrycks densiteten för alla typer av papper, kartong och tyg i gram per kvadratmeter (g/m²). Denna kvantitet kallas vanligen för grammager både på engelska och franska (ISO 536), även om många engelsktalande länder fortfarande hänvisar till "vikten". Termen densitet används här något felaktigt, eftersom densitet är massa i volym. Närmare bestämt är det ett mått på areadensiteten eller ytdensiteten.
