|---|---|---|---|
| anno (Gregorian) | a | = 365,2425 d medie, calculate ab annos commun (365 d), plus annos bissextil pro multe annos divisibile per 4. Vide anno bissextil pro detalios. | = 31 556 952 s |
| anno (Julian) | a (y, yr in anglese) | = 365,25 d medie, calculate ab annos commun (365 d), plus un anno bissextil (366 d) omne quatro annos. | = 31 557 600 s |
| anno (sidereal) | a | = tempore pro Sol de retornar al mesme position relative al stellas del sphera celestial | ≈ 365,256 363 d ≈ 31 558 149,7632 s |
| anno (tropical) | a | = tempore pro Sol de retornar al mesme position in le cyclo de saisons | ≈ 365,242 190 d ≈ 31 556 925 s |

| cyclo Sothic | = 1 461 annos de 365 d | = 4,607 4096×1010 s | |
| decennio | dec | = 10 a | = 10 × anno |
| die | d | = 24 h | = 86 400 s |
| die (sidereal) | d | = Tempore necessari pro le Terra de rotar un vice circa su axe, determinate per successive transitos de un multo distante objecto astronomic trans le meridian de un observator | ≈ 86 164,1 s |
| fortnight | fn | = 2 septimanas | = 1 209 600 s |
| helek | = 1/1 080 h | = 3,3 s | |
| hora | h | = 60 min | = 3 600 s |
| jiffy | j | = 1/60 s | = 0,016 s |
| jiffy (alternate) | ja | = 1/100 s | = 10 ms |
| ke (quarto de un hora) | = 1/4 h = 1/96 d | = 60 × 60 / 4 s = 900 s = 60 / 4 min = 15 min | |
| ke (traditional) | = 1/100 d | = 24 × 60 × 60 / 100 s = 864 s = 24 * 60 / 100 min = 14,4 min | |
| lustre (lustrum) | = 5 annos de 365 d | = 1,5768×108 s | |
| mense (plen) | me | = 30 d[1] | = 2 592 000 s |
| mense (Gregorian medie) | me | = 365,2425/12 d = 30,436875 d | ≈ 2,6297×106 s |
| mense (cave) | me | = 29 d[1] | = 2 505 600 s |
| mense (synodic) | me | Tempore cyclic del phases del Luna ≈ 29,530589 dies (medie) | ≈ 2,551×106 s |
| millennio | = 1 000 a | = 1000 × anno | |
| millidie | md | = 1/1 000 d | = 24 × 60 × 60 / 1 000 s = 86,4 s |
| minuta | min | = 60 s | = 60 s |
| momento | = 90 s | = 90 s | |
| octaeteris | = 48 me (plen) + 48 me (cave) + 3 me (plen) = 8 a of 365,25 d = 2922 d | = 2,524 608×108 s | |
| seculo | c | = 100 a | = 100 × anno |
| secunda | s | tempore de 9 192 631 770 periodos del radiation correspondente al transition inter le 2 hyperfin nivellos del stato fundamental de un atomo de caesium 133 a 0 K. (Altere secundas es rarmente usate in astronomia.) | (Unitates de base del SI) |
| septimana | sep | = 7 d | = 604 800 s |
| shake | = 10-8 s | = 10 ns | |
| sigma | = 10-6 s | = 1 µs | |
| svedberg | S | = 10-13 s | = 100 fs |
| tempore Planck | = (Gℏ/c5)½ | ≈ 1,351 211 868×10-43 s | |
| Ubi UTC es observite, le longitude del unitates de tempore plus longe que 1 s pote accrescer o diminuer per 1 s si un secunda bissextil occurre durante le intervallo temporal de interesse. | |||
