Time Conversion (a mishmash from different continuities and my own calculations):
Cybertronian Time: Human Time
1 nanoklik (Cybertronian Nanosecond): ~6 seconds
Klik (Cybertronian Second): 10 Nanokliks, 1 minute, 60 seconds
Breem (Cybertronian Minute): 80 Kliks, 8 minutes, 480 seconds
Joor (Cybertronian Hour): 45 Breems, 6 hours, 360 minutes
Cycle (Cybertronian Day): 14 joors, 84 hours, 3.5 days
Megacycle (Cybertronian Week): 25 Cycles, ~5.2 months, 12.5 weeks, 87.5 days
Stellar Cycle (Cybertron's Orbital Length): ~3.5 Megacycles, ~1.5 Earth Years, ~18 months
Orn (Cybertronian Month): 7 Megacycles, 2 Stellar Cycles, ~3 Earth years, ~36.4 months
Vorn (Cybertronian 'Year'): 28 orns, 84 Earth Years
Decavorn (10 Cybertronian Vorns): 10 Vorns, 840 Earth Years
Centivorn (Cybertronian Century): 100 Vorns, 10 decavorns, 8,400 Earth Years
Millivorn: One Million Vorns (MV), 84 million Earth Years
AN: Let me tell you guys: doing the math was not easy! Thank god I was a straight A student in math! So instead of just saying this is equal to a minute and this is equal to an hour, I also included how many of a time makes up a larger time. If that makes any sense… should I call it time scale? If anyone can help then I can edit this to make more sense.
Also, you'll notice that some Cybertronian times are either not canon length (stellar cycle being 1.5 years instead of 1) or not canon period (deca, centi & millivorns). This is my take on their times. Given Cybertron is an alien planet often depicted as not really having any sunlight, I decided to give it a wider orbit than Earth's. And since Cybertron is larger than Earth, a slower rotation. "~" is used for approximation, given some numbers I calculated had decimals. As for Vorns, given that is often depicted as 84 years, and canonically Cybertron is not as far out as Uranus (which actually completes a full orbit in 84 years!), is used to condense time frames for the very long lived species.
If you guys have any suggestions, please let me know!
