In the U.S. Customary System of measurement, 1 ton $=2000$ Ib. In the metric system, 1 metric ton $=1000 \mathrm{kg}$. Use this information to answer Exercises $69-72$.
A Lincoln Navigator weighs 5700 lb. How many metric tons is this?

Key Concepts

Dimensional Analysis

Dimensional analysis is a systematic technique used to convert units and solve problems involving different measurement systems. It involves multiplying by conversion factors that are equivalent to one, so that unwanted units cancel out, leaving the desired units. This method is crucial for accurately converting complex measurements, such as weight from pounds to metric tons.

Unit Conversion

Unit conversion involves changing a measurement from one unit to another using conversion factors. This is especially important when dealing with different measurement systems like the U.S. Customary System and the Metric System. Accurately converting between these units ensures consistency and proper communication of measurements across diverse fields and regions.

Metric System

The Metric System is an internationally standardized system of measurement used in science, industry, and everyday life, where weights are often measured in kilograms (kg) and larger masses in metric tons (or tonnes), with one metric ton equaling 1000 kg. Its base-10 structure simplifies conversion between units, making it widely adopted and easier to work with across different scientific disciplines.

U.S. Customary System

The U.S. Customary System is a set of measurement units primarily used in the United States for everyday measurements such as length, weight, and volume. In this system, weight is frequently measured in pounds (lb) and tons, with one ton commonly equating to 2000 lb. This system is distinct from the metric system and often requires conversion when comparing measures internationally.
