What are SI units and why are they important in physics?

• SI units are used only in physics and have no relevance in other scientific fields.

• SI units are important in physics because they provide a standardized and consistent way to measure physical quantities.

• SI units are not important in physics as they can be easily converted to other measurement systems.

• SI units are arbitrary and can vary depending on the country or region.

Explain the metric system and its relevance in physics.

• The metric system is only used in physics and not in any other scientific fields.

• The metric system is outdated and no longer used in modern physics.

• The metric system is a decimal-based system of measurement that is used in physics and provides a standardized and consistent way to measure and quantify physical quantities.

• The metric system is a binary-based system of measurement.

How do you determine conversion factors in physics?
