Unit System Information

Metric System (SI Units)

The International System of Units (SI) is the modern form of the metric system and is the most widely used system of measurement worldwide. It provides a coherent system of units based on seven base units.

Imperial System

The imperial system of units is a system of weights and measures used in the United Kingdom and other Commonwealth countries. It includes units like inches, feet, pounds, and gallons.

US Customary Units

The United States Customary System (USCS) is the system of units used in the United States. While similar to imperial units, there are some differences in volume measurements.
