US Fluid Drams (fl-dr) to Kannor (kanna) conversion

What is the US Fluid Dram?

The US fluid dram (also spelled fluid drachm) is a small United States customary unit of liquid volume, historically important in pharmacy and medicine for dispensing doses of liquid medication.

Definition

The US fluid dram is defined as one eighth of a US fluid ounce, or equivalently 60 minims.

$$1\ \text{fl-dr} = 0.00369669\ \text{L}$$

Since the US fluid ounce is exactly 29.5735295625 mL, a fluid dram equals 3.6966912 mL. The UK/imperial fluid drachm is slightly larger at about 3.5516 mL (1/8 of the imperial fluid ounce).

Origin and History

"Dram" derives from the Greek drachma, an ancient coin and weight. The apothecaries' system split the fluid ounce into 8 fluid drams and each dram into 60 minims, giving pharmacists a fine graduation for compounding and measuring liquid remedies.

Law and Notable Facts

The fluid dram is a legal US customary unit but is now largely obsolete in clinical practice, superseded by milliliters. Its legacy survives in the term "dram" for a small pour of whisky and in the traditional 8-dram, 1-fluid-ounce medicine bottle.

Real-World Examples and Conversions

• A single US fluid dram is about 3.70 mL, roughly three-quarters of a metric teaspoon.
• 8 US fluid drams equal 1 US fluid ounce (29.5735 mL).
• 1 US fluid dram = 60 minims ≈ 0.75 teaspoon; 1 mL ≈ 0.2705 US fluid dram.

What is the kanna?

Kannor is an archaic unit of volume, primarily used in regions of South Asia, particularly in areas of historical Kannada-speaking influence. It's important to note that the exact volume represented by a "Kannor" could vary significantly depending on the specific locality and time period. Think of it like "acre" in the west which varies in size from country to country and even from region to region. Below is more information about Kannor to answer the question.

Origin and Formation

The precise etymology of the word "Kannor" and its initial standardization are challenging to trace due to the lack of consistent historical record-keeping for local units of measurement. However, it's reasonable to assume its development was tied to agricultural practices and trade within the region. Kannor, like many traditional volume units, likely originated as a practical measure related to the capacity of common containers used for storing and transporting goods, especially grains. Its formation was influenced by the needs of local farmers and merchants.

Volume and Equivalencies

There's no universally accepted standard for the Kannor. Historically, it represented varying quantities depending on region. Here are two examples of how it was used:

• Mysore Region: In some parts of the former Mysore Kingdom, a Kannor was approximately equivalent to 128 seers (another local unit of weight), or about 128 lbs of rice.
• Other Regions: In other regions, one Kannor may have been equal to 1/4 of a koldi.

It is essential to understand that due to absence of a uniform definition, that Kannor is not used in modern practice. When you see it, it's very specific to local practice and you would have to find a local reference to understand what they mean by it.

Historical Significance and Usage

Kannor would have been used to measure grains in old times for consumption or agriculture.

Laws and Associated Figures

There are no specific laws or famous figures directly associated with the "Kannor" as a unit of measurement. Its use was largely confined to local trade and agricultural practices.

Example:

Imagine a local farmer in the 18th century, selling rice at the local market. Instead of using modern units like kilograms, they might have sold their rice in Kannors.
