Hebrew Units

Much of the information we have is made on "guesswork".

Cubic

Solid measures:
Ephah, kab / cab, omer, S'ah / seah
Omer/Homer is 1/10 of Ephah.
Letekh - 1/2 of Homer.

Solid and Liquid measures:
Homer, cor/kor

Liquid:
Log

According to Mishnah:
1 Ephah = 3 se'ah;
1 se'ah = 6 kab;
1 kab = 4 log;
1 log = 4 eggs
1 egg = approx. 55ml.

Calculated from above assumtion:
log = 330ml = 0,33 l
Ephah = bath = 24 l

Length according Cardarelli
finger = 1.0499 in. = 0.0875 ft = 2.666746 cm
palm = 4 fingers = 4.1995 in. = 10.66673 cm (trochu víc než délka moji dlaně)
zereth = 3 palms = 1.05 ft = 0.35 yd = 32.004 cm (to mi vychází jako vzdálenost od "kořene" prostředníku k loketní jamce)
cubit = 2 zaroth = 2.1 ft = 0.7 yd = 64.008 cm (přibližně vzdálenost od "kořene" prostředníku k ramenní jamce).

amah = 2 zaroth
1 mil = 2000 amoth
4 milin = 1 parasa פרסה derived from Persian parasan
1 parasa = approx. 4 Roman miles


The parasa has been described as a distance walkable in 72 minutes. (Since average walking speeds are 5 km/hr = 3.1 mi/hr, this implies a distance of 6 km = 3.7 mi. However, most estimates are shorter
Estimates of the value of the Hebrew parasa range from 3.84–4.608 km (2.4–2.88 mi).Pozn. mě trvá 2.7km za 30 minut cestou ve městě bez zdlouhavého čekání na přechodech a to nejdu ani pomalu, ani příliš rychle. Takže bych odhadoval vzdálenost spíš větší. Ale v té době neměli tak kvalitní cesty a pohodlnou obuv, tak kdoví... Zvládnout 5,4km za hodinu by se dalo, ale pokud v té době lidé nikam nespěchali a nechodili rychle jak dnes chodíme my, tak bych volil i 4,6km. V té době lidi byli zvyklí chodit pěšky dlouhé vzdálenosti mezi vesnicemi nebo městy, takže by pro ně neměl být problém zvládnout i větší vzdálenost za krátký čas. Mou rychlostí bych za 72 minut ušel 6.48 km.

The mil has been described as a distance walkable in 18 minutes. (Since average walking speeds are 5 km/hr = 3.1 mi/hr, this implies a distance of 1500 m = 1640.4 yd = 0.9 mi. Estimates of the value of the Hebrew mil range from 960–1152 m (1049–1258 yd). (Although the name came from the Roman mile, this is far less than that unit, whose length was 1472 m ( 1609.8 yd = 0.91 mi.). Mou rychlostí by to bylo 1.62km.

Etzba (2) + Tefach (8) + Zaroth(24) + Amah(48) + Ris(1600 tef.)

Etzba - min. as 2 cm = 0.79 in. and the max. as 2.67 cm = 1.05 in. = 0.09 ft .
Etzba / Etcba / Ecba (אצבע) translated as: finger, but translated as: fingerbreadth, thumbbreadth.

4 ethzbaoth = 1 tefach

Tefach - min. as 8 cm = 3.15 in. = 0.26 ft , max. as 10.67 cm = 4.2 in. = 0.35 ft .
1 Tefach = 4 etzbaoth/etcbaot

1600 Tefachim = 1 ris = 1 mil


Zereth - min. as 24 cm = 9.45 in. = 0.79 ft , max. as 32 cm = 1.05 ft = 0.35 yd .
1 zereth = 3 tefachim
2 zaroth - 1 amah

Amah min. as 48 cm = 1.57 ft = 0.52 yd , max. as 64 cm = 2.1 ft = 0.7 yd .  amah / amá (אמה, pl. אמות) - translated as cubit, ell
1 amah = 2 zaroth 2000 amoth = 1 mil

Ris - min. as 128 m = 139.98 yd = 0.08 mi , max. as 170.7 m = 186.64 yd = 0.11 mi.
1 ris = 1600 tefach
