Metric is a standard way of measuring something. In science class, you might use the metric system to measure length in meters, mass in grams, and volume in liters.

Scientists around the world use metric measurements because they're easier to work with than inches, pounds, and gallons. Everything in the metric system is based on units of ten: there are 100 centimeters in a meter, 1,000 meters in a kilometer, and 1,000 grams in a kilogram. This makes calculations much simpler than converting between feet and yards or ounces and pounds.

The word has expanded beyond physical measurements. In business, companies track metrics like sales numbers or customer satisfaction scores to understand how well they're performing. A basketball coach might use metrics like shooting percentage and assists to evaluate players. Teachers use metrics like test scores and homework completion rates to measure student progress.

When someone asks “What metrics are you using?” they want to know exactly how you're measuring success or progress. Good metrics give you clear, objective information rather than vague feelings or guesses.
