How Many Grams Are in a Stone - Grams to Stones and Stones to Grams Conversion

Feel free to convert grams to stones and stones to grams using our conversion chart, conversion calculator, and learn the relationship between these two units.

Conversion Formulas

Conversion of grams to stones and stones to grams is an easy one since both units are used for measuring mass. And while gram is a unit of the SI system of units, obviously the stone is not a unit of the SI system of units and is not used often anymore.

One stone (st) is a unit of mass defined as having exactly 14 pounds, while one pound (lb) is defined as having exactly 0.45359237 kg or 453.59237 grams.

Thus we can find the relation between gram (g) and stone (st):

M_(stone) = 14 Pounds = 14 * 0.45359237 kg = 6.35029318 kg = 6350.29318 g = ~6350.3 g

M_(gram) = M_(stone) / 6350.29318 = 0.00015747304 st

So, one stone equals ~6350.3 grams and one gram equals ~0.000157473 stones.

Stone (st) as a unit of mass is mostly used for measuring the weight of the human body (sports events, for example, boxing) and very rarely in trade.

Over time, different values for stone were used, but after standardization 1 (one) stone is 14 pounds (pounds are also standardized to 0.45359237 kg), making the conversion from stone to grams and grams to stones much easier.

Grams to Stones and Stones to Grams Conversion Examples

How many grams are 4 stones?

In order to calculate the mass of 4 stone in grams, we use the following formula:

M = 4 Stone = 4 * 6350.29318 g = 25401.17272 g = ~25401 g

So, 4 stones equal ~25401 grams.

How many grams are 16 stone?

In order to calculate the mass of 16 stone in grams, we use the following formula:

M = 16 Stone = 16 * 6350.29318 g = 101604.69088 g

So, 16 stones equal 101604.69088 grams.

How many stones are 1500 grams?

In order to calculate the mass of 1500 grams in stones, we use the following formula:

M = 1500 g = 1500 / 6350.29318 = 0.236209566 st

So, 1500 grams equal 0.236209566 stones.

Obviously, because of the large Stone:Gram ratio (~6350.3 : 1), conversion of extra-large amounts of stones to grams and extra-small amounts of grams to stones doesn't make much sense ... mostly :)

Stones vs. Grams: Brief History

Throughout history, the measurement of weight has been vital to trade, science, and daily life. Two units—stones and grams—represent distinct approaches to weight measurement, each with its own historical significance.

The stone, a traditional unit primarily used in the UK, and the gram, a metric unit embraced worldwide, highlight the evolution of weight standards across time and regions.

The Stone: A Historical Unit

The stone as a unit of weight has ancient origins, dating back to early civilizations that used large stones as standard measures for trade. The use of stones for weight was widespread throughout Europe, but their value varied by region and by the item being measured. For example, a stone of wool might weigh differently than a stone of wheat. This lack of uniformity made trade more complex, especially across borders.

In medieval England, efforts were made to standardize the stone. By the 14th century, under King Edward III, the stone was fixed at 14 pounds (approximately 6.35 kilograms) for general use, particularly in trade involving wool.

This 14-pound stone became the standard across England and later in the UK, where it continues to be used informally today, especially for measuring body weight. While the stone has mostly been replaced by kilograms in most contexts, it remains culturally significant in the UK and Ireland.

The Gram: A Product of the Metric Revolution

In contrast to the stone’s ancient and regional use, the gram emerged from the scientific rationalism of the late 18th century. During the French Revolution, the need for a universal and standardized system of measurement became clear. The metric system, introduced in 1795, was designed to bring order and consistency to measurements across science, industry, and commerce.

The gram was defined as the mass of one cubic centimeter of water at its maximum density. It became the base unit of mass in the metric system, and over time, the system was adopted by nearly every country in the world. The gram and its larger counterpart, the kilogram, have since become the global standard for measuring weight. The simplicity and precision of the metric system, with its decimal structure, made it ideal for scientific use and international trade.

Stones vs. Grams: Cultural and Practical Differences

The use of stones and grams represents more than just different systems of measurement; it reflects broader cultural and historical differences. Stones, deeply rooted in tradition, are still used colloquially in the UK for describing personal weight, offering a sense of familiarity. The unit’s long history ties it to an era when measurement systems were largely local and varied.

Grams, on the other hand, embody the precision and universality of modern science and global commerce. The metric system’s adoption has been essential for international consistency, allowing for seamless trade, scientific research, and industry across borders. While the gram is ubiquitous in most countries, its impact is most strongly felt in industries that require precision, such as pharmaceuticals, food production, and manufacturing.

The stone and the gram serve as symbols of two distinct eras in the history of weight measurement.

The stone, with its origins in ancient and medieval trade, carries a sense of tradition, particularly in the UK.

The gram, born out of the metric revolution, stands as a testament to the drive for global consistency and scientific accuracy.

While the world increasingly relies on grams and kilograms for precision, the enduring use of the stone reflects the cultural importance of long-standing systems of measurement.
