Final answer:
The metric system is the scientific measurement used worldwide, known for its simplicity of using multiples of ten. It includes meters, liters, and grams and forms the basis of the International System of Units (SI), which is the standardized system used in scientific measurements.
Step-by-step explanation:
The scientific measurement system primarily used in science around the world is the metric system. This system is standardized on multiples of ten, which simplifies the conversions between units. The fundamental units of the metric system include the meter for length, the liter for liquid volume, and the gram for mass. Unlike the customary system used in the United States, which consists of feet, inches, pounds, cups, and gallons, the metric system's use of a base 10 system makes it much easier to work with in scientific calculations and is universally accepted in the scientific community. Scientific measurement often refers to the International System of Units (SI), which is an internationally agreed-upon standard that includes the metric system and is composed of seven base units.
