MATH 101D From Inch to Metric Measurement

Описание: In this video, we introduce the metric system as it’s actually used in manufacturing, with a focus on millimeters, not abstract math or textbook theory. You’ll learn why metric measurement was designed the way it was, how it differs from inch-based measurement, and how to safely move between inches and millimeters when you need to.

   • Math 101 - Math for Manufacturing  

This lesson is part of the Math 101 series, designed for adult learners, workforce training, and anyone preparing for machining, inspection, welding, or technical manufacturing roles.

In this video, you’ll learn:

Why the metric system was created and why it’s widely used in manufacturing

How meters, centimeters, and millimeters relate to each other

Why millimeters are the standard unit for parts and features

How to visualize metric sizes compared to inches

How to convert inches to millimeters and millimeters to inches using 25.4

Why conversion helps with understanding, but does not make parts interchangeable

This video is intentionally low stress and practical. The goal is not speed or memorization, but confidence — knowing what system you’re working in and avoiding costly mistakes before they happen.

Whether you’re new to manufacturing, returning to the workforce, or just trying to make sense of metric drawings and measurements, this video will give you a solid foundation.
