what is the need for measurement?

there are lots of reasons, for one, if youre going to decorate your house youll have to measure the things you want to get to make sure theyll fit inside...also, if you wanted to put a pool in your backyard youd have to measure it to see if it would fit...or, if you wanted to put an object ontop of something delecate, youd have to weigh it to make sure it wont break...if youre cooking you have to measure your ingredients to make sure youre making the dish right...if youre going on a trip youll want to know how many miles youll be traveling to know how much gas youll need...there are LOTS of reasons we need measurement, everyone uses it in their everyday life...without it the simple things we do everyday would be very difficult

It usually depends on who your customer is.  If you mean metric or inches.  Automotive, Medical uses metric, but most other industries still use inches.  I am automotive mostly we use ISO as a dimensioning Standard

Physics, major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the effects of these forces. \n\nMeasurement, finding the size or amount of some quantity, and expressing it as a number of defined units.All measurement is based on a comparison. In general, the thing to be measured is compared with something that has already been calibrated, or measured against a known reference. However, a measurement is not complete unless it includes a statement of its uncertainty, or the confidence one can have in it.\nUnits of Weight and Measurement\nImperial System\nAMOUNT NAME \nAngular or Circular Measure \n60 seconds = 1 minute (min) \n60 minutes = 1 degree \n30 degrees = 1 zodiac sign \n57.2958 degrees = 1 radian \n90 degrees = 1 quadrant or right angle \n360 degrees = 1 circle \nCubic Measure (Volume) \n1,728 cubic inches (cu in) = 1 cubic foot (cu ft) \n27 cubic feet = 1 cubic yard (cu yd) \n231 cubic inches = 1 US gallon (gal) \n277.27 cubic inches = 1 British imperial gallon (i gal) \n2,150.42 cubic inches = 1 US bushel (bu) \n2,219.36 cubic inches = 1 British imperial bushel (i bu) \nDry Measure (Capacity) \n2 pints = 1 quart \n8 quarts = 1 peck (pk) \n4 pecks = 1 bushel \nLinear Measure (Length) \n1,000 mils = 1 inch (in) \n12 inches = 1 foot (ft) \n3 feet = 1 yard (yd) \n5.5 yards = 1 rod (rd) \n40 rods = 1 furlong (fur) \n8 furlongs = 1 mile (mi) \n5,280 feet = 1 mile \n3 miles = 1 league (l) \nLiquid Measure (Capacity) \n4 fluid ounces (fl oz) = 1 gill (gi) \n4 gills = 1 pint (pt) \n2 pints = 1 quart (qt) \n4 quarts = 1 gallon (gal) \nMariners’ Measure \n6 feet = 1 fathom (fath) \n120 fathoms = 1 cable’s length (US Navy) \n1,852 metres = 1 nautical mile (n mi) \n1 nautical mile per hour (n mph) = 1 knot (k) \nPaper Measure \n25 sheets = 1 quire (qr) \n20 quires = 1 standard ream (rm) \n516 sheets = 1 printers’ ream \n2 reams = 1 bundle (bdl) \n4 bundles = 1 case (c) \nPrinters’ Measure (Typography) \n0.013837 inches = 1 point \n12 points = 1 pica \nSquare Measure (Area) \n144 square inches (sq in) = 1 square foot (sq ft) \n9 square feet = 1 square yard (sq yd) \n30.25 square yards = 1 square rod (sq rd) \n160 square rods = 1 acre \n640 acres = 1 square mile (sq mi) \nSurveyors’ Measure \n7.92 inches = 1 link (li) \n66 feet = 1 chain \n80 chains = 1 mile \nWood Measure \n144 cubic inches (1' x 1' x 1'') = 1 board foot (bd ft) \n16 cubic feet (4' x 4' x 1') = 1 cord foot (cd ft) \n8 cord feet = 1 cord (cd) \nWEIGHTS \nWeight (Apothecaries’) \n20 grains = 1 scruple (s ap) \n3 scruples = 1 dram (dr ap) \n8 drams = 1 ounce (oz ap) \n12 ounces = 1 pound (lb ap) \nWeight (Avoirdupois) \n27.3438 grains = 1 dram (dr) \n16 drams = 1 ounce (oz) \n16 ounces = 1 pound (lb) \n14 pounds = 1 stone \n100 pounds = 1 hundredweight (cwt) \n8 stones = 1 long hundredweight \n(l cwt) \n2,000 pounds = 1 short ton (ST) \n2,240 pounds = 1 long ton (LT) or 20 (l cwt) \nWeight (Troy) \n24 grains = 1 pennyweight (dwt) \n20 pennyweights = 1 ounce (oz t) \n12 ounces = 1 pound (lb t) \n\nMiscellaneous Units\nWEIGHT/MEASURE UNITS \nAbsolute zero = -273.15o C (-459.67o F) \n1 atmosphere = 760 mm of mercury \n1 cup = 10 fluid ounces \n1 carat (international) = 200 milligrams (gem weight) \n1 megaton = 1,000,000 tons \n3 teaspoons = 1 tablespoon \n1 angstrom unit = 0.1 nanometre \n1 bolt of cloth = 40 yards \n1 gross = 12 dozen, or 144 \n1 light-year = 9.46 x 1012 km \n(5.88 x 1012 mi) \n1 tablespoon = 1/2 fluid ounce

I think that you need to make your question more clear.  I for one am unsure of what you are askiing-\n\n\nHowever- observation is very important and so are rubrics.

Tell us what you mean, and perhaps we can tell you how to measure it.

Why do you need it?\n\nDo you mean divide?

What is required for definite measurement for any volume is a sense of boundary. Therefore, we could estimate the volume of the universe, but we aren't sure.  Therefore it's pure speculation.\n\nIn terms of liquids, they do have a defined boundary by the changes of the index of refaction from when light enters the liquid.  Therefore, with a predefined container that has calibrated unit of measurement, one can easily determine the volume of liquid for a given temperature and pressure.  Remember, liquids can expand and contract due to changes of pressure and temperature, although the changes in volume do not change sinificantly.\n\nOn the other hand, a gas that is lighter than air would be very difficult to maintain within a system to measure directly.  Given a closed container, with a definite pressure and temperature, you could estimate the amount of volume that the gas should fill.  Rememeber, since it's lighter than air, the mass would be difficult to measure, unless you had a airflow meter to measure gas flow by mass.  The result should be the same for every repeated condition, a certain amount of mass should fill the vessel to a specific pressure at the given temperature.  On the other hand, gases that are heavier than air should be more easier to measure their volume; this case can only be applied to gases that has a define boundary due to color.  Therefore, at a specific temperature and pressure, you could estimate their volume and measure their mass.\n\nIn measuring gases, usually volume is correlated to temperature and pressure.  Usually, the best thing to define about any liquid or substance is the density at a given temperature and pressure.  This will undoubtedly define the physical property of the object at those conditions.

My dear friend you need two more dimensions ie., length and breadth to calculate that.

Metric. Thy still use the same ones.

The word you're looking for is "measured"..?

If it's just for the room itself, you measure the length of the room and the width of the room and draw that rectangle on a sheet of paper and label the edges with the actual measurements you found.\n\nMore details you could add would be location of electrical outlets and light fixtures, doors and windows (all with measurements of their size and location).

SI unit for length is 'meter'

Metric measurements are a typically European concept.\n\nBear in mind most people agree that Computers will play a great role in the future, and they aren't metric why should anything else be. 16 bit, 32 bit, 64 bit - do they sound metric to you?\n\nI'd rather stick to miles and gallons, pounds and ounces etc.

I would give an example if I could understand the question.  Perhaps you meant, "Why are measurement formulas expressed with variables?"\n\nIt is so that you can plug in the values that you observe and calculate the formula.  \nExample:  Area of rectangle = B * H\nB = base, H = height\nSo you can use this formula whenever you know the value of these two variables, for ANY rectangle.\n\nI hope this has answered your question; again, it wasn't clear.
