What is 1/60 of a second called?

I don't think there's a special name for the unit of time that's 1/60th of a second. Unlike mass and distance, time's measured in a funny way. That's primarily because we can divide time into years (the amount of time it takes the earth to revolve around the sun) or days (the amount of time it takes for the earth to spin about its axis). Since the ratio of those two quantities is approximately 1 to 365.25, you're going to get all sorts of crazy things like leap years happening.Compound that with the fact that old calendars LOVED the number 360 because it's divisible by a LOT of numbers, and you get all those weird conversions like 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute. Fortunately, the insanity stops there...seconds are generally subdivided into either milliseconds (a thousandth of a second) or microseconds (a millionth of a second). I suppose you could have centiseconds (0.01 seconds) and kiloseconds (1000 seconds), but those units just aren't used enough to be popular.... Show More

It is called a "tierce". If you look it up on Wikipedia you will find it as the fifth or sixth definition. However, for the time period after Middle English, the most common use of "tierce" in vernacular speech would be 1/60th of a second. When referring to volume or mass this would be clear from context. For an interesting discussion of why we should use the tierce, Wikipedia has a good article on the ꜱɛҳagesimal based numbering system used by every ancient culture that was mildly advanced. It explains why we have minute and second "accent" marks (which are to explain the value of the exponent of 60). If you want to skip it, the reason is the amount of numbers that may be cleanly divided into 60. Makes fractions simple. Using a 360 based numbering system would be even more advantageous to a non-computerized world but 360 symbols is too much, though there are ways around this also.
