Metric McMaster

Metric McMaster automatically converts imperial units to metric as you browse McMaster-Carr product pages. Unlike other converter extensions, Metric McMaster is specifically designed to handle the unique formatting and measurement styles used on the McMaster website, ensuring accurate and reliable conversions where other tools fail. When you visit mcmaster.com, the extension detects measurements in inches, feet, pounds, and Fahrenheit, and displays their metric equivalents directly on the page. Simply hover your mouse over any imperial unit to see its metric conversion as a tooltip. You can toggle these helpful tooltips on and off at any time by clicking the extension’s toolbar button. This extension is ideal for engineers, students, and anyone who prefers to view metric units when sourcing parts, making it easier and faster to understand product specifications without manual calculations or switching tabs.
