It is because the length of each person varies.But SI units show exact length whenever it is taken.
The scientist who is credited with discovering the SI (International System of Units) is Gabriel Mouton, a French clergyman and mathematician. He proposed the system in 1670. The SI system is now the most widely used system of measurement worldwide.
Scientists typically use the International System of Units (SI) to collect data. This system includes units such as meters, grams, seconds, and Kelvin. These units provide a standardized way for scientists to measure and communicate data across different fields of study.
Scientists use a single system of units, such as the International System of Units (SI), to ensure consistency, accuracy, and ease of communication between researchers worldwide. Using a standardized system avoids confusion and errors that can arise from the use of different units in scientific measurements and calculations.
The SI unit named after the scientist who described the transfer of pressure in an enclosed fluid is the pascal (Pa), named after Blaise Pascal and defined as one newton per square meter.
The SI unit for temperature is the kelvin.
Most scientist and countries use it.

No its false
The SI unit is the Kelvin, but we use Celsius a lot too.
most of the world does SI so more people can understand with it in SI units
Scientist do use the metric system, they may refer to it sometimes as the SI system. Only three countries in the world haven't fully converted to metric, Liberia, Myanmar(Burma), and U.S.A, and even in these countries most scientist use the SI system.
There is no SI unit of sailing
Oh yes, scientists only use metric SI units.
Celsius and Kelvins are the two scales that scientists use to measure temperature and the official SI unit for temperature is Celsius.
The idea is to use an international standard - the same units everywhere.
Most scientists use the Metric system of units of measure, also called the Système international or SI system
they are units for scientist
