The maintenance of honest weights and measures was an important principle in Biblical times. God himself directly commanded his people to be honest when they traded and not attempt to cheat each other (especially those who were strangers).
The stranger (alien) that dwells with you shall be to you as one born among you, and you shall love him as yourself . . . You shall do no unrighteousness in judgment, in measures and weights, or in quantity. You shall have just balances, just weights, a just ephah, and a just hin . . . (Leviticus 19:34 - 36, HBFV).
Wise King Solomon also taught that maintaining honest standards of trade was critical to the success of God's people. Using different sized weights and measures, for the purpose of cheating others, was an abomination to the Eternal (Proverbs 20:10, 23).
The Bible states that greedy merchants were known to use undersized measures when selling commodities like grain. They also would weigh a buyer's money using extra heavy weights so that they could steal even more gold or silver (Amos 8:4 - 5).
Below is a list of the King James Bible words that refer to the most commonly used measurements. The information listed is a consensus from a variety of Bible commentaries, dictionaries and other study aids. Please note that the values used below are only estimates.
1 ephah = 22 liters = 5.8 Gallons
Used in the Bible for liquids (1Kings 7:26, Isaiah 5:10).
44.5 to 52 centimeters = 17.5 to 20.4 inches
The length of a cubit is based on the distance between the tip of the middle finger and the elbow (Genesis 6:13 - 16, Matthew 6:27, Luke 12:25).
There were at least two sizes of cubits used in the Old Testament. The first or ordinary cubit was about 17.5 inches (44.5 centimeters) long. The second, known as the long or "royal" (sacred) cubit, was a hand-breadth longer (see Ezekiel 40:5, 43:13) or about 20.4 inches (51.8 centimeters) long. The royal cubit was likely used by Solomon to build Jerusalem's temple (2Chronicles 3:3) and possibly utilized to construct Noah's Ark.
32 kilometers = roughly 20 miles
This distance is used only once in the New Testament (Luke 2:44).
10 omers = .62 bushels = 22 liters = 20 dry quarts
Used in the Bible for a dry measure (Exodus 16:36, 1Samuel 17:17).
2 mites = 1/4th of a cent
Used only three times in the New Testament as a measure of money (Matthew 5:26, 10:29, Mark 12:42).
34 liters = 9 gallons
Used only once in the New Testament in reference to Jesus' miracle of turning water into wine (John 2:6).
1/8th of a mile = 201.2 meters
Translated from the Greek word stadion and used as a measure of distance (Luke 24:13, John 6:19, 11;18, Revelation 14:20, 21:16).
1/20th of a Shekel = .57 grams = .02 ounces
The smallest weight and piece of money used in Israel (Exodus 30:13, Leviticus 27:25, Numbers 3:47).
7.6 centimeters = 3 inches
Used for lengths (1Kings 7:26, Psalm 39:5).
1/6th of a Bath = 3.7 liters = 1 Gallon
Used as a measurement of liquids (Exodus 29:40, 30:24, Numbers 15:4).
Dry Measure: 10 Ephahs = 211 liters = 6.2 bushels

Can be used to measure volume of dry commodities like barley or liquids (Numbers 11:32, Hosea 3:2, Ezekiel 45:11, 13 - 14).
1/72 of a bath = .3 liter = 1/3 of a quart
Used as a measure of liquid (Leviticus 14:10, 12, 15, 21, 24).
Translated from the Hebrew maneh as "pound." Used as a measure of currency (1Kings 10:17, Ezra 2:69, Ezekiel 45:12).
1/2 Roman quadran = 1/2 farthing = 1/8th of a cent
Translated from the Greek word lepton, it was the smallest coin used (Mark 12:42, Luke 12:59, 21:2).
1/10 ephah = 2.2 dry liters = 2 dry quarts
The Hebrew word omer is also sometimes translated as "sheaf" or "sheaves" (Leviticus 23:10 - 12, Ruth 2:7). A sheaf was considered a quantity of grain big enough to bundle (Exodus 16:22, 32 - 33, 36).
Penny (KJV Bible)
1 Penny = 1 Roman Denarius = 1 Greek Drachma
In the KJV New Testament, the same Greek word denarion (denarius) is translated as "penny" (Matthew 20:2 - 13, 22:19, Revelation 6:6), "pennyworth" (Mark 6:37, John 6:7) and "pence" (Matthew 18:28, Mark 14:5, Luke 7:41). Jesus used a denarius to teach that it was lawful to pay Roman taxes (Matthew 22:19, Luke 20:22 - 25). One denarius was considered a single day's wages.
Used as Weight: 100 shekels
Used for Money: 100 Roman denarii = 100 Greek drachmas = $16.00 U.S.

3,000 shekels = 60 minas = 34.3 kilograms = 75 U.S. pounds
One of the common Biblical weights also used to value money (Exodus 38:24 - 29, 1Kings 9:14, Matthew 18:24, Revelation 16:21).
