Great Gross (gr-gr) to Long Hundred (long-hundred) conversion

What is great gross?

Great Gross is a rather uncommon unit of quantity, mainly used historically in commerce and inventory management. Let's explore its definition, formation, and some examples.

Defining Great Gross

A great gross is a unit of quantity equal to 12 gross, or 144 dozens, or 1728 individual items. It is primarily used when dealing with large quantities of small items.

Formation of Great Gross

The great gross is formed through successive groupings:

• 12 items = 1 dozen
• 12 dozens = 1 gross (144 items)
• 12 gross = 1 great gross (1728 items)

Thus, a great gross represents a significantly larger quantity than a gross or a dozen.

Common Usage & Examples

While not as common today due to the adoption of more standardized units and digital inventory systems, great gross was historically used for items sold in bulk:

• Buttons: A haberdasher might order buttons in great gross quantities to ensure they had enough for various clothing projects.
• Screws/Nails: A hardware store could purchase small screws or nails in great gross to stock shelves.
• Pencils: A large school district might order pencils in great gross for the entire year.
• Small Toys: A toy manufacturer might produce small toys in great gross quantities for distribution.

Historical Significance and Laws

While there isn't a specific "law" directly tied to the great gross unit, its use highlights historical trade practices and inventory management techniques. There aren't any famous people directly associated with "Great Gross." Its significance is rooted in the pre-metric system era where base-12 calculations were prevalent. These concepts came from ancient Sumaria and Babylonia.

Modern Relevance

Today, while great gross might not be a common term, the concept of bulk ordering remains relevant. Businesses still consider quantity discounts and economies of scale when purchasing supplies, even if they are measuring those quantities in different units.

Volume Calculation

If you were to calculate the volume of items in great gross you could use following formula

$V_{greatgross} = N * V_{singleitem}$

Where:

$V_{greatgross}$ is volume of the items in great gross $N = 1728$ the number of items in Great Gross $V_{singleitem}$ is the volume of a single item

What is long hundred?

The long hundred, also known as a great hundred or a twelve-score, is an obsolete unit of quantity equal to 120 items. It's a relic of a counting system where calculations were sometimes done in base-12 or base-20, rather than the standard base-10 system we use today.

Origin and Formation

The long hundred arises from the practice of counting in dozens (groups of 12). Unlike the "short hundred" (decimal hundred) that contains 100 items, the long hundred is based on a duodecimal system influence or simply a traditional way of counting specific goods. It is formed by multiplying twelve (a dozen) by ten, resulting in 120.

• Dozen: 12 items
• Long Hundred: 12 dozens, or 12 * 10 = 120 items

This contrasts with the decimal system, where a hundred is simply 10 * 10 = 100.

Historical Context and Usage

The long hundred was most commonly used in trade and commerce, particularly when dealing with goods that were easily grouped into dozens, such as eggs, nails, or other small wares. It provided a convenient way to count and package these items. While no specific laws directly mandated its use, it was a customary practice deeply ingrained in certain industries.

Examples of Quantities Using Long Hundred

Here are a few examples of how long hundreds might be used:

• Nails: A hardware store might sell nails in long hundreds, making it easier to manage inventory.
• Herrings: In the herring trade, fish were often counted and sold using the long hundred.
• Other small wares: Any items that were easy to bundle into dozens could be sold using this unit.

Let's say you are buying nails, then

1 Long Hundred = 120 nails.

So buying 3 long hundreds would get you 360 nails.

$$3 \times 120 = 360$$

Why did long hundreds cease to exist?

The adoption of the metric system and decimal-based accounting practices gradually led to the decline and eventual obsolescence of the long hundred. These modern systems provided greater efficiency and standardization.
