Weight and Mass

Weight and mass are two commonly misunderstood terms in fluid mechanics and mechanics. Weight is the measurement of the gravitational force on an object, while mass is the measurement of the amount of matter in an object.

What instrument measures mass?

   User Avatar 
   Traditionally a balance was used to measure mass. Objects of known or accepted mass was balanced against another object of unknown mass. When the balance was level the two pans had the same mass. The term balance or scales is still used even though there is no balance used. The scales were the pans that the objects sat on. Now electronic balances are used that gauge the mass of the objects. While you can measure mass with a spring loaded scale, it is less accurate than a balance as it relies on a spring loaded to a specific acceleration of gravity for any given mass. A change in altitude will change the results given on the scale, due to the actual change in gravitational force (it is small at only about 0.031% error for every kilometer increase in altitude)*. A balance would experience no such change as the mass of an unknown quantity is compared to the mass of a known quantity, thus negating any effects of gravity. Another instrument that measures mass is an inertial balance. An inertial
   balance doesn't require gravity to work, so it can be used in space. It measures the mass of an object by attaching it to a spring and seeing how it affects the spring's period of oscillation. Very tiny masses can be measured directly (using a "massometer"). But we normally use scales, which measure weight, which is directly proportional to mass (a property of matter equal to its resistance to a change in speed or direction of travel). The mass of an object is the same everywhere in the universe. Its weight, however, changes depending upon its location: a bowling ball has greater weight on the surface of the Earth than it does on the Moon. Great confusion arises when people interchange units of weight with units of mass. Scientists, particularly physicists, are very careful about not using the terms interchangeably, but regular folks have no choice for practical applications. For example, when you weigh a regulation ten-pin bowling ball, the scale will tell you it "weighs" between 4 and 7
   (3.63 to 7.27 actually) kilograms, even though the kilogram is, technically speaking, a unit of mass, not weight. You can also measure the mass of an object using a scale, as long as you factor in the gravitational constant (G). For instance, in an environment with only 1/2 the gravity of That on earth, you would have to double the weight displayed on the scale to determine the actual mass. As an example, 10Kg of lead in a 0.5G environment would only "weigh" 5Kg on a scale...half as much as on earth, even though its mass is unchanged.

How many pounds are in a kilogram?

   User Avatar 
   One lb is 0.454 kg, so a tad more than 2. 1 kilogram = 2.2 pounds. (2.20462262 to be more precise). 22 pounds = 10 kilos The formula to convert kg to lbs 1 kg * 2.2046 lbs = 2.204622622 lbs kg and lbs can't be equated, since they're units of different types of quantities. The "kg" is a unit of mass, whereas the "lb" is a unit of force. On Earth, 1 kg of mass weighs 2.205 pounds. In other places, the same 1 kg of mass has a different weight. Formula: pounds x 0.454 = kilograms

How do you convert litres into pounds?

   User Avatar 
   There is no equivalence. A pound is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a litre of air. How many pounds? Next consider a litre of water. How many pounds? The masses of equal volumes of the two substances will clearly be very different. There is no direct conversion between mass and volume: You need to know the density of the substance to enable you to carry out the conversion. If you can find the density of the substance (grams) then to convert the amount of litres to pounds: Convert it to kilograms to maintain the same unit Multiply the number of kilograms by 2.20462 (pounds/ kilogram) The result will be the amount of litres of the substance in kilograms

How many grams are in a tablespoon?

   User Avatar 
   It depends on what you're measuring. What's the tablespoon holding? Butter or oregano? Sugar or salt? Molten lead or feathers? Grams are a unit of mass (or weight) and a tablespoon is a unit of volume. Therefore it depends entirely on what you are measuring -- it depends on the density of the substance. A tablespoon of lead will be much heavier than a tablespoon of feathers (although a gram of lead and a gram of feathers weigh exactly the same!). Similarly, a tablespoon of butter weighs a different number of grams than a tablespoon of salt. See the Web Links for a handy automatic conversion calculator. Just enter the food item, the units you have, and the units you want... and presto! For instance (for US tablespoon): 1 tablespoon of water weighs 14.79 grams 1 tablespoon of table salt weighs 18.25 grams 1 tablespoon of butter weighs 14.19 grams 1 tablespoon of oil (canola or soy) weighs 13.62 grams 1 tablespoon of sugar (granulated) weighs 12.5 grams 1 tablespoon of sugar (brown) weighs
   13.8 grams (packed) Some other useful conversions: 16 tablespoons = 1 cup 3 teaspoons = 1 tablespoon 28.35 grams = 1 dry ounce 1 US tablespoon = 14.7867648 ml

What is mass divided by weight?

   User Avatar 
   Answer #1: It's (1) divided by (the acceleration of gravity in the place where that mass has that weight): weight = mass x g (where g is the acceleration due to gravity) ⇒ mass/weight = mass/(mass x g) = 1/g On the earth, g ≈ 9.81 ms-2 ⇒ mass/weight ≈ 1/9.81 ms-2 ≈ 0.102 m-1s2 On the moon, g is approx 1/6 that of the earth, ⇒ mass/weight ≈ 6/9.81 ms-2 ≈ 0.612 m-1s2 If the questioner really meant weight divided by mass it gives the acceleration due to gravity in that place otherwise I'm not sure of a use of knowing the reciprocal of the acceleration due to gravity that the questioner asked. ============================= Answer #2: If you ask a scientist, that's true answer in the sense that a mass M experiences a gravitational force Mg and if you measure weight in units of force (which nobody does). But anyone else would be surprised to learn that a mass M (say 10 grams) would have a weight of anything else but M grams (10 grams). Sometimes expressed as "grams weight" often just
   grams for short. If you pick up a Kilogram, even a scientist would say "its weight is 1 kilogram". The gravitational force on it is 1g, so if you let it go it will accelerate at a rate force over mass, which is g. So the answer depends on your units of mass and weight. That's why science lessons tend to avoid use of "weight". In outer free space mass would be measured by (say) tension in the string if you whirl it on the end of it around your head, but the weight (measured by a spring balance) would be zero (precisely as described in the first answer above, with g=0). ============================== Answer #2.1: The problem with discussing mass and weight in the same units, and the reason that this masked contributor is waging a one-man battle to make the distinction recognized and acknowledged by users of this website, is the new problem that you have now that the space age is here. As long as we were all irrevocably bound to the Earth, one kilogram of mass would always weigh one kilogram,
   if you like it that way. We could afford to be sloppy about it, with hardly one out of ten men-on-the-street knowing or caring about the difference, and nobody ever had a problem with it. But now that some of us have already slipped these surly bonds ... and among the general population, the younger you are, the better the chance that you will do so one day before you're done ... those who ignored the distinction begtween mass and weight all through school, or never even encountered it there, are poised to step into an inconvenient pile. Because as soon as you pack for your trip to anywhere else away from Earth, and take along your lucky kilogram, you're due for a shock when you step out at your destination: Your kilogram doesn't "weigh" a kilogram there. It weighs something else. If you're on the moon, for example, your kilogram weighs 0.165 kilogram ! That's the shock I'm trying to avoid, because if you think the straight dope is too complex for people to handle now, you haven't seen
   anything yet.

How many grams of cinnamon does a teaspoon hold?

   User Avatar 
   You cannot directly really convert g (a solid measurement) to ml or teaspoonfuls (a liquid measurement). In an ounce, however, is 30ml or 28.3g. 30 ml is 2 tablespoonfuls, 3 teaspoonfuls in a tablespoon. I would say it is approximately 5g since there are 5ml in a teaspoonful and 28.3 and 30 aren't too far apart.
