What Does thousandth Mean
The adjective thousandth , or thousandth , comes from the Latin word millesĭmus . The first meaning mentioned by the Royal Spanish Academy ( RAE ) in its dictionary refers to that which, in order, appears after the ninety-ninth ninety-ninth .
The thousandth edition of something, therefore, is number 1000 . This is the edition after the ninety-ninety-ninth (999).
When the adjective is applied to a part, it refers to one of the thousand identical parts in which the division of a whole is made . In this sense the term can also be used as a noun.
It is called a millisecond to one thousandth of a second . That is to say: if we divide 1 second into a thousand parts, each of these fragments is one thousandth (one millisecond).
The thousandths of a second are extremely short chunks of time . In colloquial language , the notion is often used symbolically to refer to what is very fast. For example: “When they asked me to join this team, I did not hesitate for a thousandth of a second” , “The young man finished crossing the track and, a few thousandths later, the train sped past” , “For a few thousandths of a second I didn't understand what was happening until I realized what was happening… ” .
The use of thousandths of a second is relevant in many sports . In motorsports , one thousandth can define the winner of a competition. Take the case of qualifying for a Formula 1 grand prix : the runner who completes a lap of the circuit in the shortest time, long first. If driver X did a lap in 1: 35.497 and driver Y did it in 1: 35.498 , driver X took first place by just one thousandth.
The concept of thousandth is also related to decimal numbers . In the field of mathematics, a decimal number is known as that which is represented by means of an integer and a fractional part, separated by a comma or, in other countries, by a period. When we cannot express a quantity using a whole number , we resort to decimals; This is very common in the market environment, where prices usually include a part that can be paid in bills (the whole) and another that requires coins (the fractional).
To read and write the decimal numbers, we must first consider the integer part, as we can see in the following example: 2.6 can be read "two point six". Although in this case the comma is read by its name, the same is not always the case; in the case of prices, it is replaced by the word "with": "This television costs 499.95 (four hundred and ninety-nine ninety-five . " Another difference that we can notice between the numbers in general and the prices is that in The latter can write a fractional part of a single digit but read it as if it were a ten, if we know that it refers to a quantity in coins that is a multiple of ten: 4.9 it reads "four and ninety."
Now, decimal units are obtained after dividing an integer, that is, the number 1, into equal parts. If the number of parts is ten, it is spoken of tenths; if it is one hundred, hundredths; if it is thousand, thousandths. If we go back to the above examples and want to write "one thousandth of a second" technically, we must do so using the following expression : 0.001 second .
When we divide a whole number into a thousand parts, we get a result with a comma and followed by three digits, one for every zero in the number 1000. In elementary school, teachers often explain to children that 1 moves to the right "a space for every zero ”, and in this way it is easy to remember the tenths, the hundredths and the thousandths.
