What is the formula for converting hours, minutes and seconds?

One hour equals 60 minutes and one minute equals 60 seconds.

Currently, each day and night is 24 hours long, and in ancient times it was 12 hours long. When western mechanical clocks and watches were introduced to China, people called the Chinese and western time points, respectively, "big time" and "hour". With the popularization of clocks and watches, people gradually forget the "big time", while the "hour" is used.

Ancient Timekeeping Units in China

Shakti, nin, instantaneous, finger-snapping, roku, and short period of time.

Twenty kshasas are one nen, twenty nen are one instant, twenty instant are one snapping finger, twenty snapping fingers are one loppong, twenty loppongs are one shuriken, and one day and one night are thirty shurikens.

According to the Indian Monastic Law, "A ksana is a thought, twenty thoughts are an instant, twenty instantaneous are a snapping finger, twenty snapping fingers are a loppong, twenty loppongs are a sushumi, and a day and a night are thirty sushumi."

Accordingly, it can be deduced that if a day and a night are counted as 24 hours, there are 96 million "moments", 4.8 million "thoughts", 240,000 "moments", and 12,000 "moments". There are 12,000 "snap fingers", 600 "roku", and 30 "moments".
