Thus density is an intensive quantity. The SI derived unit for density is the kilogram per cubic meter (kg/m3). This unit is awkwardly large for most chemical applications. The unit g/cm3 and its equivalent, g/mL, are more commonly used for solid and liquid densities.
Q. What is derived quantity give examples?
Derived quantities are the quantities which are expressed in terms of fundamental quantities and based on seven basic fundamental units. For example, area,volume,force,pressure,density etc are few derived quantities.

Q. Which is the derived physical quantity?
Mass, Length & Time are fundamental physical quantity while velocity is derived physical quantity.
Q. Why is density called derived unit?
Density is a derived unit because it’s not reported as a pure unit. (A pure unit would be something like kilograms or meters.)
Q. What is the smallest unit of mass?
ounces
Q. Which is bigger G or NG?
“Nanograms” (ng) and “milligrams” (mg) are both units of grams. “Nano” means one-billionth. Therefore, a nanogram is a billionth of a gram. One milligram is equal to one million nanograms.
Q. How small is a picogram?
The picogram (pg) is a unit of mass in the International System of Units, defined as 10-15kilogram using the SI prefix system.
Q. What is a picogram?
: one trillionth of a gram.
Q. What is smaller than a microgram?
Units of mass
| Value | SI symbol | Name |
|---|---|---|
| 10−1 g | dg | decigram |
| 10−2 g | cg | centigram |
| 10−3 g | mg | milligram |
| 10−6 g | µg | microgram (mcg) |
Q. Is KG smaller than g?
Using this table as a reference, you can see the following: • A kilogram is 1,000 times larger than one gram (so 1 kilogram = 1,000 grams). Here is a similar table that just shows the metric units of measurement for mass, along with their size relative to 1 gram (the base unit).
Q. What is the smallest gram?
Metric Units
| Milligram(mg) | 0.001 gram or 11000 gram |
|---|---|
| Centigram(cg) | 0.01 gram or 1100 gram |
| Decigram (dg) | 0.1 gram or 110 gram |
| Gram(g) | 1,000 milligrams |
| Dekagram (dag) | 10 grams |
Q. How many nanograms are there in a mass of 2 Exagram?
Exagram to Nanogram Conversion Table
| Exagram [Eg] | Nanogram [ng] |
|---|---|
| 2 Eg | 2.0E+27 ng |
| 3 Eg | 3.0E+27 ng |
| 5 Eg | 5.0E+27 ng |
| 10 Eg | 1.0E+28 ng |
Q. Is a vector a ray?
1 Answer. Vector and ray are symbolized the same way: a line segment with an arrow on one end but they are very different things. A vector has a direction and a magnitude (for example, 5 km south-east). A ray has just a direction and a starting point, and it has infinite length.
Q. What is the end of a vector called?
The tail of the vector is the starting point of the vector, and the head (or tip) of a vector is the final, pointed end of the arrow. Figure 4.
