I'm working on a series and attempting to create a more universal set of units. For this post, I will simply ask this: Is it feasible to redefine the meter to be the distance light travels in 1 second so that the unit is a whole number of: 300,000,000m. (Instead of the current 299,792,458m) . This would make the new meter (let's call it a Standard Meter) 0.9993081933...m. The downside to this is that it relies on the current arbitrary second. But I think, for the sake of sanity, it would be nice to keep that as it is because it does have a scientifically defined time. The second part to this is a product of a new standard year, which is 30,000,000 seconds. Each minute is 100 seconds. Each hour is 100 minutes. Each day is 10 hours (100,000 seconds which is just under 28 "Earth hours"), each month is 30 days and there are 10 equal months. The new standard year would be very similar to a traditional Earth year, only defined off of something that is standardized. Bottom line I am getting to, is this would make a light year 9.0Pm (Petameters) exactly. Does this make sense and is it feasible to construct a world/universe around this for a series of hard sci Fi stories?
Edit: Just to clear up a few things. The new Standard System I am proposing will not be linked to any planet, but it will refer to similar times based on Earth times. This will be for human and Earth biological entities. The new standard will use the second as it is based off the current second (dealing with the Cesium atom). I understand that the meter has a scientific definition off the speed of light, I just want to know if it is reasonable to alter that definition to create a whole number that will make general space travel and time keeping easier and more universal. To summarize 1 standard second = 1 Earth Second 1 Std. minute = 100 seconds 1 std. day = 100,000 seconds 1 Std. year = 30,000,000 seconds 1 m = 1/300,000,000 of a second of c. Which would make c=300,000,000 m/s I know I could also redefine the second to be a more rounded number, but I think the second should stay as it is.
