In ancient timekeeping each hour was two hours long! So how many quarters are there in an hour? How much time is an hour?

Quarters are calculated using an hourglass, and an hour is then divided into approximately 4.167 quarters, a quarter is 14.4 minutes.

Quarter - Ancient timekeeping with a funnel.

The funnel pot is divided into two parts: the sowing pot and the receiving pot. Sowing kettle divided into two to four layers, are small holes, can drip water, and finally into the receiving kettle, the receiving kettle with standing arrows, arrows engraved on the score of 100 engraved, arrows with the gradual rise of the water storage, revealing the number of engraved, to show the time.

A 24-hour day and night for 100 moments, which is equivalent to the current 1440 minutes. It can be seen that each moment is equivalent to 14.4 minutes. Therefore, "three moments at noon" is equivalent to 11:45 and 12 seconds at noon

Extended Information

The hourglass was designed to prevent water from affecting the accuracy of timekeeping due to changes in temperature. Its principle is to push the gear set by flowing sand so that the pointer indicates the moment on the hour disk. The earliest record of this is found in the Yuan Dynasty.

One, according to the timing method

Leak pot according to the timing method can be divided into two kinds: arrow leakage and said leakage.

Arrow leakage: arrow leakage is through the water scale to measure the time leakage pot.

Second, arrow leakage is divided into two kinds:

One is to observe the container of water leakage to reduce the situation to measure time, called the leakage of water leakage pot (also known as sinking arrow leakage).

The other is to observe the increase of water inflow into the container (without holes at the bottom) to measure the time, called the water leakage type funnel (also known as floating arrow funnel).

In some ancient civilizations, such as China, Egypt, Babylon, etc., have used the funnel.

Weighing leakage: weighing leakage is to drip the weight of water to measure the time leakage pot.

Three, the funnel pot is also known as the funnel carving, the ancient use of dripping water, sand how much to measure the time of an instrument.

According to the medium of flow can be divided into water leakage and hourglass. According to the timing method can be divided into arrow leakage and weighing leakage. A variety of leakage pot leakage pot due to different principles in the structure of the differences also exist.

Water leakage is a pot of water, the use of water equalization drip principle, the observation of the pot in the carving of the arrow on the data displayed to calculate time. The history can be traced back to the Xia and Shang Dynasties.
