Convert between biblical and modern units of measurement — cubits, shekels, ephahs, and more
📖 Gen 6:15
1 ammah = 0.444 m
1 ammah = 0.444 m
| Unit | Equivalent in m | 📖 |
|---|---|---|
| 1 finger (Finger (Digit)) | 0.0185 m | Jer 52:21 |
| 1 tefach (Handbreadth) | 0.074 m | Ex 25:25 |
| 1 zeret (Span) | 0.222 m | 1 Sam 17:4 |
| 1 ammah (Cubit (Standard)) | 0.444 m | Gen 6:15 |
| 1 r.cubit (Royal Cubit) | 0.518 m | Ezek 40:5 |
| 1 qaneh (Reed (Measuring Rod)) | 2.67 m | Ezek 40:3 |
| 1 stadion (Stadion (Furlong)) | 185 m | Luke 24:13 |
| 1 shabbat (Sabbath Day's Journey) | 888 m | Acts 1:12 |
| 1 day (Day's Journey) | 32000 m | Num 11:31 |
Genesis 6:15 gives the Ark's dimensions as 300 cubits long, 50 cubits wide, and 30 cubits tall. Converting: 300 cubits = 133.2 meters (437 ft), 50 cubits = 22.2 meters (73 ft), 30 cubits = 13.3 meters (44 ft). That is roughly the size of a modern cargo ship.
1 Samuel 17:4 records Goliath at 6 cubits and a span. Converting: (6 × 0.444) + 0.222 = 2.886 meters (9 feet 6 inches). The Septuagint records only 4 cubits and a span (1.998 m / 6 ft 7 in), which is still extraordinarily tall.
John 2:6 describes 6 stone jars holding 2-3 metretes each. Converting: 6 jars × 2.5 metretes × 39.4 liters = approximately 591 liters (156 US gallons) of wine — enough for a very large wedding celebration.
Biblical measurements are approximate by nature — there was no universal standardization in the ancient Near East. The values used here represent scholarly consensus based on archaeological evidence (measuring rods, weight stones, vessel fragments). Different scholars may give slightly different values, typically within a 10-15% range.
The standard cubit (ammah) is based on the distance from elbow to fingertip, approximately 44.4 cm (17.5 in). The royal cubit, used in Ezekiel's temple measurements, adds a handbreadth (about 7.4 cm), making it approximately 51.8 cm (20.4 in). The Egyptian royal cubit was similar at 52.4 cm.
A talent of silver weighed about 34.2 kg (75.4 lbs). In Jesus's parable of the talents (Matthew 18:24), the servant owed 10,000 talents — approximately 342,000 kg of silver. At modern silver prices, that would be hundreds of millions of dollars, emphasizing the parable's point about immeasurable debt and forgiveness.
