Really cool Time & Date calculator which converts between units easily. * CALCULATE using dates, times, years, days, hours, minutes, & seconds. * CONVERT between all above units. * Includes MULTIPLICATION, SUBTRACTION, ADDITION, & DIVISION. * Simple design - very powerful functionality * EASILY & RAPIDLY INPUT dates, times, or both * Perform calculations in the units of your choice, then convert the answer to any other unit * Track how long until an event or how long since one occurred Examples: - If I ran a 5k in 20:09, then what was my pace?: 20:09 ÷ 3.1 = 6:30. - What if I took about 7 seconds off my pace, then how long would it take to complete my workout?: 6:30 - 7 = 6:23 × 3.1 = 19:48. - If I do 30 second reps 12 times, how much total time did it take?: 35 seconds × 12 = 7m 00s. - How many minutes is 8 hours? - Exactly old is someone born on 4/8/1985? - How many seconds? - How long has it been since we first met? - When is 6 weeks from today? - How many seconds in 30 years? - How many days is 1,000,000 seconds? - What about hours? Answer these, and other time-related questions! Crunch Time. Please feel free to contact us at support@alumra.ltd with any questions or feedback. As always, we'd love to hear from you!

It offers a fun and practical way to approach time measurement, especially for scientific or engineering contexts.

Highlights
  • Convert time to and from metric units
  • Tell time in metric
  • Measure time in metric
  • Uses seconds as the base unit

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.
