Why is it easy to change from one unit to another in the metric system?
The metric system is the preferred system of scientific units for several reasons: The majority of countries in the world employ the metric system of measurement. Because metric units are decimal-based, they are easily converted by moving the decimal point.

Although NASA has ostensibly used the metric system since about 1990, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units.
Why does NASA use metric?
The agency has decided to use metric units for all operations on the lunar surface, according to a statement released today. The change will standardize parts and tools. It means Russian wrenches could be used to fix an air leak in a U.S.-built habitat.

The United States has official legislation for metrication; however, conversion was not mandatory and many industries chose not to convert, and unlike other countries, there is no governmental or major social desire to implement further metrication.
WHAT IS A in dimensional formula?
Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. These will specify the nature of the unit and not its magnitude.
What is dimensional formula of resistance?
Therefore, resistance is dimensionally represented as M L2 T-3 I-2.
What is density dimensional formula?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
