Video and Audio Production<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In digital media, time is measured in <strong>frames<\/strong> and <strong>samples<\/strong> \u2014 both of which are derived from seconds. A 3-hour film at 24 frames per second contains:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>10,800 seconds \u00d7 24 fps = <strong>259,200 frames<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p>Audio engineers deal with sample rates (typically 44,100 or 48,000 samples per second). Three hours of CD-quality audio:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>10,800 \u00d7 44,100 = <strong>476,280,000 samples<\/strong><\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Legal_and_Financial_Contexts\"><\/span>5. Legal and Financial Contexts<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Lawyers, consultants, and freelancers often bill by the hour \u2014 but contracts and time-tracking software sometimes require precision down to the minute or second. Payroll systems, overtime calculations, and contract enforcement may all require exact time conversions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Everyday_Life\"><\/span>6.

We have 60 seconds in a minute and 60 minutes in an hour. Why?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Ancient_Babylonian_Legacy\"><\/span>The Ancient Babylonian Legacy<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The 60-based (sexagesimal) system comes from <strong>ancient Babylon<\/strong>, around 2000 BCE. The Babylonians used base-60 for mathematics because 60 is a highly composite number \u2014 it&#8217;s divisible by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30. This made it incredibly useful for division and fractions before decimals were invented.<\/p>\n\n\n\n<p>The Babylonians divided the day into 12 &#8220;double hours&#8221; (a nod to base-12 counting, which also has ancient roots \u2014 you can count to 12 on one hand using the three segments of each of your four fingers). The Greeks divided those into 60 minutes each, and then into 60 seconds.<\/p>\n\n\n\n<p>By the time we had better number systems, clocks and sundials had already been built around the sexagesimal system for thousands of years. It stuck.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Hierarchy_of_Time_Units\"><\/span>The Hierarchy of Time Units<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Here&#8217;s how the main time units relate to each other:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Unit<\/th><th>Equals<\/th><\/tr><\/thead><tbody><tr><td>1 millisecond<\/td><td>0.001 seconds<\/td><\/tr><tr><td>1 second<\/td><td>1,000 milliseconds<\/td><\/tr><tr><td>1 minute<\/td><td>60 seconds<\/td><\/tr><tr><td>1 hour<\/td><td>60 minutes \/ 3,600 seconds<\/td><\/tr><tr><td>1 day<\/td><td>24 hours \/ 1,440 minutes \/ 86,400 seconds<\/td><\/tr><tr><td>1 week<\/td><td>7 days \/ 604,800 seconds<\/td><\/tr><tr><td>1 year (approx.)<\/td><td>365.25 days \/ 31,557,600 seconds<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fun_Facts_About_10800_Seconds\"><\/span>Fun Facts About 10,800 Seconds<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Since we&#8217;ve established that 3 hours = 10,800 seconds, let&#8217;s put that number in perspective:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>10,800 seconds<\/strong> is how long it takes light to travel approximately <strong>3.24 billion kilometers<\/strong> (or about 21.6 times the distance from Earth to the Sun).<\/li>\n\n\n\n<li>In <strong>10,800 seconds<\/strong>, the International Space Station completes nearly <strong>2 full orbits<\/strong> of the Earth (one orbit takes about 92 minutes, or 5,520 seconds).<\/li>\n\n\n\n<li>A <strong>hummingbird&#8217;s heart<\/strong> beats roughly 1,200 times per minute.
