The metric unit for mass is the kilogram. For smaller masses, as in this case, you may also use grams or milligrams.
kg for kilogram
It would depend on the density of the substance. Litres measure volume; kg measure weight.
The best unit to measure the mass of 10 pennies would be grams (g). Milligrams (mg) would be too small a unit for this measurement, as it is typically used for very small masses. Kilograms (kg) would be too large a unit, as it is typically used for much heavier objects. Grams strike a balance between these two extremes and are commonly used for measuring the mass of small objects like coins.
kg is a mass, ml is a volume. However with water, 1 kg = 1 liter = 1000ml
1,000,000 mg = 1 kg → 65 mg = 65 ÷ 1,000,000 kg = 0.000065 kg
mass of a substance or an object
The SI unit of mass is the kilogram (kg).
Mass is measured in kilograms (kg) in the SI system of measurement.

Weight is a measure of the gravitational pull for a mass , such that a mass of 1 Kg is having a weight of 10 Newton . So weight is a downward force measured in Newtons . Weight ( in N ) = Mass ( in Kg ) × Gravity ( usually 10N/Kg )
Kilograms (kg) is used to measure mass
kl
kg. (kilograms), or tons (thousands of kg.).
1 kilo is normally used to refer to 1 kilogram. This is a measure of mass and is NOT the same as weight. A mass of 1 kg is a mass of 1 kg - wherever it is.
472 kg refers to mass, which is a measure of the amount of matter in an object.
This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, kg is a measure of weight or mass.
