Time Conversion Chart

Time Conversion Chart is a bright, ready-to-print classroom poster that keeps every unit of time in one clean reference students can find at a glance. Instead of pausing to remember how many seconds are in an hour, learners look up the group they need and read the equivalence.

The poster sorts time into three color-coded tables — Clock Time (seconds, minutes, hours), Calendar Time (days, weeks, months, years), and Long Time (decades and centuries) — each listing the unit and exactly what it equals, from 1 minute = 60 seconds to 1 century = 100 years. A friendly pig mascot checking his grandfather clock makes it inviting on any classroom wall.

A full-width Quick Conversion Rule answers the question students ask most: moving to a larger unit means divide, moving to a smaller unit means multiply, with worked examples like 2 hr = 120 min and 3 days = 72 hr to anchor the idea.

Print it poster-size for the wall or hand it out as a reference sheet for notebooks, centers, and homework. Grade-neutral and standards-aligned for upper-elementary measurement and time work.
