Math 101C - Math for Manufacturing: Decimals & Precision

This video explains how decimals are used for real-world measurement in manufacturing and machine shop environments. Building on fractions and the number line, we show how common tape-measure fractions convert to decimals, why decimals are easier to use with calculators, and how place value relates to tenths, hundredths, and thousandths of an inch. Using hands-on demonstrations with precision measuring tools, gauge blocks, and an optical comparator, the video introduces shop terminology like “thou” and explains why exact dimensions exist as ideals, while real manufactured parts must fall within allowable tolerances. This lesson is designed for workforce training, machining fundamentals, and manufacturing math learners who want to better understand precision measurement and tolerances. https://youtube.com/playlist?list=PLxm8xqzftfmmpIceBd-pjzprLL_ZYlLYL&si=vFW_oGXv_MxVrw9L Music: "Last Train North" by TrackTribe • Instagram: / tracktribemusic • TikTok: / tracktribeofficial • Facebook: / tracktribemusicofficial
