About Quarters

Typical Use Cases

The quarter (also called quarter hundredweight) is a historical British imperial unit primarily used in agricultural contexts and commodity trading. It was commonly employed for measuring grain, produce, and livestock. Today, quarters appear mainly in historical documents, antique scales, and traditional British agricultural references. Understanding this conversion is useful for historians, collectors of antique weighing equipment, and those studying historical trade records or Victorian-era commerce.

Historical Background

The quarter derives from the imperial hundredweight (cwt) system, where 1 quarter equals 1/4 of a hundredweight, or 28 pounds (12.7006 kg). In medieval and early modern Britain, quarters were standard for grain measurement—both by weight and by volume. The term "quarter" also referred to a volume measure (approximately 8 bushels), which sometimes causes confusion in historical texts. The weight-based quarter largely fell out of use in the 20th century as metric measurements gained prevalence.

Conversion Tips

When converting grams to quarters for historical research, verify whether the source refers to weight or volume quarters, as both existed. This converter uses weight quarters (12,700.6g = 1 quarter). For quick reference: 1kg ≈ 0.079 quarters, so 10kg ≈ 0.79 quarters. Since quarters are large units, conversions from small gram amounts will yield very small decimal values. This unit is rarely needed outside of historical contexts or specialized agricultural applications in Britain.

Frequently Asked Questions

How many grams are in a quarter?

One quarter (quarter hundredweight) equals 12,700.6 grams or 12.7 kilograms. This is equivalent to 28 pounds or 1/4 of an imperial hundredweight.

Is the quarter still used today?

The quarter is largely obsolete in modern commerce. It appears primarily in historical documents, antique equipment, and traditional British agricultural contexts. Most modern applications have switched to metric units (kilograms) or US tons.

What's the difference between a weight quarter and a volume quarter?

A weight quarter equals 28 pounds (12.7kg), while a volume quarter equaled approximately 8 bushels for grain. Historical texts may use "quarter" for either measurement, so context is important when interpreting old records.

About Our Conversion Standards

Our weight conversions are based on the International System of Units (SI) and standards published by the National Institute of Standards and Technology (NIST). All conversion factors are accurate to at least 6 decimal places, ensuring precision for both everyday and professional use.
