Grams. Matter is measured by mass and mass's main unit is grams.

Use a protractor.
Metric system: meters; customary system: feet
The quantity of matter in an object is its mass. If you then know what the object is made from you can find out (approximately) how many atoms or molecules it has (measured in mol).
L or mL L Litres, millilitres or fluid onces
The quantity of matter in an object is its mass. If you then know what the object is made from you can find out (approximately) how many atoms or molecules it has (measured in mol).
Electronic balances automatically find the mass of an object and provides the mass on a screen for you. A triple beam balance requires you to manually find the mass of an object and find the measurement.
Matter is defined as anything that has mass and volume. Mass is the amount of matter in an object. Volume is the amount of space an object takes up.
Perimeter is the distance around an object. Area is the total amount of space inside the object. Length is the the measurement of one side of the object. Length is added up to find the perimeter. Length is multiplied to find the area.
It depends on what kind of material the matter is made of. Find the weight of the object, divide by 10 or 9.8 you should find the mass.
Drop it into a measurement device such as a graduated cylinder with enough liquid to cover the object. Assuming the object sinks, the increase in mls is the volume of the object (1 ml = 1 cm^3)
You cannot make a conversion, they are measuring two separate things. A running meter is a measurement of distance or length. A square meter is a measurement of area. If you run the parameter of an object, you will have to know more about the object to find out the square meters.
