Time is one of those things that are measured in more or less standard ways throughout the world. There are no different English or metric units for time. Rather, most of modern civilization uses the same basic measurements, most of the time. The conversion of time is concerned with the ascending degree of units.
Here's how you convert time measurements.
- A thousand nanoseconds is equivalent to one microsecond.
- A thousand microseconds is equivalent to one millisecond.
- A thousand milliseconds is equivalent to one second.
While these units may seem really quick and not practical in telling time, they serve their purpose in more precise industrial processes. For instance, in computing for CPU processes, a nanosecond can make a difference, especially if you consider millions and millions of processes.
As for the units we are more familiar with, these might take time getting used to.
- Sixty seconds is equivalent to one minute.
- There are sixty minutes in one hour.
- There are twenty four hours in one day.
- There are seven days in a week.
- Two weeks are considered as a fortnight.
- Four weeks converts roughly to one month. The regular calendar month has 28 to 31 days.
- Twelve months make up a year.
- A year has 365 days - except during leap years. Leap years are years that are divisible by 4. During these years, an extra day is added at the end of February, making the total of the year 366 days.
- Ten years is a decade.
- Twenty years is a score.
- One hundred years is a century.
- Ten centuries or a thousand years is equal to a millennium.
With this guide, you can, for instance, convert time measurements into something you are more familiar with. For instance, 150 minutes in hours would be 150 divided by 60, which is two, with a remainder of 30. Therefore, 150 minutes would be equal to two hours and 30 minutes. This is certainly easier to monitor and measure using one's wristwatch or clock, rather than counting 150 minutes from start to end.
You might notice that the different units of time are somewhat a mix between metric and non-metric types of measurements. For instance, the use of "nano," and "milli" when splitting up thousandths of a second is much like the metric system. The use of the terms "century" and "millennium" meanwhile, are indicative of latin "cent" meaning hundred, and "milli" meaning thousand.
Another useful way to convert time does not necessarily involve measurements, but time zones. Because of the different time zones around the world, you might be familiar with different time settings, such as in the USA there is Central time, Eastern time, Pacific time, and the like. These usually come with an offset from the Greenwich Mean Time or GMT, which is a point in the UK that stands at "0H." Pacific time is -0700H GMT, which means it's seven hours behind GMT. Central time is -0500H GMT, at five hours behind GMT, while Eastern time is -0400H GMT, which means it's four hours behind GMT.
You might also be familiar with the use of "UTC," which is the coordinated universal time, which is the more accurate means to measure time, compared to GMT. UTC takes into consideration the slowing down of the Earth's rotation, and therefore compensates time by adding or subtracting a few seconds at certain intervals during the day.
Time conversion may be complicated because of the different units and factors involved. But it should be a cinch if you make sure to work on only one conversion at a time.
