Answer:
Most scientists use the International System of Units (SI) as the system of measurement when collecting data and doing experiments. The SI system is a standardized system of measurement used internationally and is based on seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity). The use of SI units helps to ensure consistency and accuracy in scientific research and allows for easy comparison of results between different experiments and researchers.
