## What is Metric Seconds?

Sixty seconds per minute, sixty minutes per hour, 24 hours per day, seven days per week. When you’re trying to do math with time, it’s hard. Metric Seconds is easy. Use this app to convert time to and from metric, and to tell and measure time in metric.

Metric seconds is time measured in seconds using the standard metric units that are easy.  The zero point is midnight January 1, 1970, the "start of time" for UNIX and other computer systems.  And there are no time zones in metric time, it's all UTC-based.

In metric time, seconds are the base unit.  Then the regular metric multipliers are used: kilo, Mega, Giga, etc.  We can use “hecto” for 100 seconds to have something close to a minute.  Kiloseconds, 1000 seconds, are about 16 minutes long so 3.6 ksec is an hour and 86.4 ksec is a day.

Science fiction has used metric time. Some examples are Vernor Vinge’s books A Fire on the Deep and Deepness in the Sky and Charles Stross’s books Glasshouse, Accelerando, and Neptune’s Brood. Also Robert Forward and Iain M. Banks used metric time.

We won't abandon minutes and hours anytime soon. We’re all used to them. We won't start saying things like “I’ll be right with you, give me a hectosec.” For doing math with time or doing scientific and engineering measurements, kiloseconds, Megaseconds, and Gigaseconds might just make a lot of sense. And trying something new is fun.

### 5/5 — Awesome app!

*2024-04-12*

Just what I was looking for.

### 5/5 — Unix time in stopwatch

*2023-11-29*

The app is great.  It would be almost perfect if the stopwatch showed the start and stop UNIX times to hundreth of sec for each lap.   That would be valuable for example for timing astronomical events and other events that  depend on both date-time and duration.  Also a button to save the log to a note or copy it.

### 5/5 — Very cool!

*2021-10-24*

This app is interesting and fun and gives us a new way of thinking about time.
