A ge is a way to measure. 
A ge is a way to measure volume. 
In Japan, a gō can measure rice. It can also measure a cup of sake. Some rice cookers even come with a small cup. This cup helps you measure the right amount. It is a very helpful tool for cooking.
A ge is a unit used to measure volume. Volume is how much space a liquid or solid takes up. This unit is traditional in China. In China, one ge is equal to ten sheng. Its exact size has changed over time. In 1930, a law set it to a deciliter. A deciliter is 0.1 liters. 
Korea also uses a unit based on the ge. In Korea, it is called a hop. Today, one hop is equal to 0.18 liters. This is the same as the Japanese gō. In Japan, the gō is often called a cup. It is used to measure rice or sake. Many rice cookers include a small cup for this. One gō of rice is about 150 grams. 
In Japan, people also use the gō for climbing. They divide a mountain path into ten parts. Each part is called a gō. These are like stations on a long trail. The gō can even measure area. In that way, it is equal to a tsubo. A tsubo is about 0.33 square meters.
Have you ever wondered how people measure liquids or grains? A ge is a traditional unit used in China. It is a way to measure volume. Volume tells us how much space something fills. One ge is equal to ten sheng. This unit helps people measure things fairly. It has been used for a very long time. 
In China, the exact size of a ge changed. The Beiyang Government set a value in 1915. Later, a law in 1929 changed it again. This new law started on January 1, 1930. It made one ge equal to a deciliter. A deciliter is 0.1 liters. In 1959, the People's Republic of China kept this value. They called the deciliter a fēnshēng. 
Korea also has a unit based on the ge. In Korea, this unit is called a hop. It is also known as doe or toe. The size of the hop has changed over time. During an occupation, Korea used Japanese measures. Today, one hop is 0.18 liters. This is the same size as the Japanese gō. Using it for business is against the law in South Korea. 
In Japan, the unit is called a gō. It is often called a cup. One gō is about 180.4 milliliters. This is about 0.18 liters. People use it to measure rice or sake. You might find a small cup in a rice cooker. One gō of rice is about 150 grams. Sake bottles often hold about four gō. 
The gō can be used in other ways too. It can measure an area called a tsubo. A tsubo is about 0.3306 square meters. Climbers in Japan use the name for mountains. They divide a mountain path into ten parts. Each part is called a gō. These parts act like stations on a trail. It is a very useful word for many things. 
The ge is a traditional unit of volume used in East Asia. Volume measures the amount of space an object or substance occupies. This unit is part of a long history of regional measurement systems. It is closely related to units used in China, Korea, and Japan. While the name changes across borders, the underlying concept remains similar. It helps people measure liquids and dry goods like rice or sake. 
In China, the ge is a fundamental unit of measurement. It is defined as being equal to ten sheng. The exact size of a ge has changed throughout different eras. This happened because the size of the sheng itself changed over time. In 1915, the Beiyang Government established a specific value for the ge. Later, the Nationalist Government passed the Weights and Measures Act in 1929. This law became effective on January 1, 1930. It set the ge equal to one deciliter. A deciliter is a metric unit equal to 0.1 liters. The People's Republic of China confirmed this value in 1959. They gave the deciliter the official Chinese name of fēnshēng. However, they allowed traditional Chinese medicine pharmacists to use traditional amounts. This exemption was meant to help them prepare medicine correctly.
Korea also utilizes a traditional unit based on the ge. In Korea, this unit is known as the hop. It is also referred to as doe in South Korea or toe in North Korea. The value of the hop has varied alongside the size of the doe. During a period of occupation, Korean native measures were standardized. They were changed to match their Japanese equivalents. Today, the present-day hop is equal to 0.18 liters. This is the same volume as the Japanese gō. In South Korea, using the hop for commercial purposes is criminalized. However, the unit continues to be used in North Korea.
Japan uses a version of this unit called the gō. The gō is often referred to as a cup. It is also based on the ge and equals 0.18 liters. The Japanese government officially equated the gō with liters in 1891. One gō is approximately 180.4 milliliters. This is roughly equal to 6.35 imperial fluid ounces or 6.10 US fluid ounces. It is also about 0.4 metric cups. 
The gō serves many practical roles in Japanese daily life. It is the traditional amount for a serving of rice before cooking. It is also a standard serving for a cup of sake. In many kitchens, a 1-gō measuring cup is included with rice cookers. These may be the traditional size or a 180mL metric equivalent. In dining, one gō of rice is sometimes equated to 150g of short-grain rice. The unit also applies to serving sizes for fugu and other types of fish. Because sake bottles usually hold 720 or 750mL, they hold about four gō.
Beyond volume, the gō can represent different types of measurements. It is used as a unit of area equal to a tsubo. One tsubo is approximately 0.3306 square meters. The term also appears in the context of Japanese mountaineering. Climbers divide the distance from a mountain foot to its summit into ten gō. These ten parts are often called "stations" in English. This allows climbers to track their progress along a route.
The history of the ge shows how measurement systems evolve. These units connect different cultures through shared mathematical roots. They demonstrate how local traditions interact with modern metric standards. From medicine in China to rice in Japan, the unit remains relevant. It bridges the gap between ancient customs and modern precision.
