gram {g}
An appropriate metric unit of mass for a pencil would be grams.
The appropriate unit of mass for dust is typically grams (g) or milligrams (mg), depending on the amount of dust being measured. These units are commonly used to measure small and light particles like dust.
"Liters" is a unit of measurement in the metric system used to measure volume.
Inches are a unit of length, while kilograms are a unit of mass. You cannot directly convert kilograms to inches. If you are trying to convert 46.8 kilograms to a different unit of mass, such as pounds, you can then convert the resulting weight to inches using the appropriate conversion factor.
A cup of rice weighs between 6oz to 7oz depending on the type of rice length of grain etc.. (The previous answer stated: "A cup of rice weighs one cup. A cup is a unit of measurement." Cup is a unit of VOLUME measurement not weight.)
All the grains in a bag of rice is only 5 digits long. To take it to the next level, I then calculated the volume of this rice to be about .02604 cubic feet. So 100 digits worth of rice (10^99 minimum) would require over 5.7 x 10^92 cubic feet or approximately 3.9 x 10^81 cubic miles. To make that fit into your head a little nicer, that's 1.5 x 10^70 earth volumes.
Personally, I would measure the length of a grain of rice in millimeters.
A grain of rice is several milligram. A large paper clip might weigh as much as a gram.
An appropriate metric unit of mass for a pencil would be grams.

1 Dhan (weight of one wheat berry) = 4 Grain of Rice. Measure of length is Gaz.
