Kilograms
Is it practical for a student to measure the mass of liquid reagents for experimentation in kg or pounds?
Neither. Both are dry measures, not liquids so not applicable since different liquids weigh differently by volume. For example, 1 gallon of water weighs 8.34 lbs whereas 1 gallon of gasoline weighs only 6.15 lbs so selecting reagents by any unit of weight is impractical as one would have to know specific weights of the reagents. Reagents are measured by liquid volume, ounces (oz), quarts (qt) and gallons (gal) for standard measure, liters (L) or fractions thereof, i.e. milliliters (ml) for metric measure, which is the world scientific standard. To convert volume to mass: a. Look up liquid's density as it is expressed in units of "g/ml" ("d"). b. Next, measure the volume of the liquid in a graduated cylinder ("v"). c. The weight of a liquid in grams is the product of its density and volume: dv = weight conversely: v = weight/d Imagine the nightmare of working any of this out in lbs and oz - metric rules!

Can you measure the length of a dog in kilograms?
No, kilograms is a measure of weight. You would measure it in meters or centimeters.
What do meters and liters and kilograms measure?
Meters measure length, liters measure capacity, and kilograms measure weight.

Are kilograms usually used to measure volume?
False. Kilograms measure mass. Liters measure volume.
Do you measure a bicycle in grams or kilograms?

How many meters are in 3.01 kilograms?
Kilograms can't be converted to meters. Kilograms measure mass, while meters measure length.
How many millimeters are in 4.2 kilograms?
Millimeters can't be converted with kilograms. Millimeters measure length, while kilograms measure mass.
What can you measure with?
kilograms
