Anything which occupies space is called 'Matter'. You can measure the quantity of any 'Matter' by measuring it's Volume ( in cubic inches, or cubic feet, or cubic Centimetre or cubic Metre etc.). You can also measure the quantity of Mass (Weight) which it has, expressed in kilogram, or gram, or tonne, or pound, or ounce, or ton etc. The word 'weight' technically is by definition, the force of gravity acting upon some 'mass'. The force of gravity is different in value at different places on our planet. Therefore a mass will have a different weight in different parts of the world. This is the reason why a world standard of a Kilogram is kept in a temperature and humidity controlled atmosphere in a special room in Paris. Very accurate copies of this kilogram are made and sold to other nations , and they then know that every kilogram in the entire world , has the same mass.
The SI unit of mass is kilogram.
Kilogram or gram.
Grams.
Liters.
Measuring the temperature with adequate instruments.
milliliters
There is no such thing. There are different units, depending on what exactly (what physical quantity) you want to measure.
Acceleration or deceleration is measured in metres per second2 (ms-2).
To measure, or measuring is the use of units to find a size of quantity
There are no units for measuring the use of temperature.
degrees
You always use square units when measuring area.
No, unless you are asked to provide the answer in certain units.
Liters.
Relative value is a dimensionless quantity, and so it shouldn't matter what units you want to use, as long as you are consistent.
Measuring the temperature with adequate instruments.
Surface area is measured in square units.
Scientist use the "Internation system of Units" to measure the properties of matter
No. I would use linear units if measuring the swim distance or cubic units if measuring the volume of water. Square units might be useful to see how many people could use the pool before it got crowded but that would depend on whether they were there for swimming or splashing about.
If measuring weight - use a scaleIf measuring mass - use a balance in units of grams or kilograms.If measuring size (L x W x H) - Use a ruler/tape measureIf measuring volume - use a graduated cylinder.
