If you have ever looked for info on the TV show “Two A Days”, then you will undoubtedly have如果您有任何時候都找信息，電視節目“兩個1天” ，那麼你無疑將有 Googled googled it.它。 And, you will have found the show’s MTV page, its Wikipedia entry and the tv.com site discussing the show.和，你會發現顯示的MTV在網頁上，其文字的入口和tv.com網站的討論顯示。

But, what on earth, you may ask is that Google calculator entry that appears above the results?但是，什麼地球上，你可能會問，是Google的計算器進入出現上述結果呢？

“two a days = 2.31481481 × 10-5 hertz” “兩個1天= 2.31481481 ã - 10月5日赫茲”

It has to be some kind of Google “joke” right?它必須是某種形式的Google “的笑話”的權利？ Well, here’s the skinny and we are not talking latte:那麼，這裡的瘦和我們現在談的不是拿鐵：

Hertz (Hz) is the unit of frequency in “per seconds”, the reciprocal of time.赫茲（ Hz ） ，是該單位的頻率在“每秒” ，相互的時間。 One per second equals 1 Hz.一每秒等於1赫茲。 There are usually 86400 seconds in a day, so “two a day” would be 2 divided by 86400 in hertz.有通常86400秒在某一天，所以“兩節” ，將2除以在86400赫茲。 Which is 2.31481481 × 10 ^-5這是2.31481481 ã - 10 ^-5

Obvious when you know how!很明顯，當你知道如何！ What Google fails to do with its calculator is recognize that this number is not an irrational number like什麼樣的Google未能做到與它的計算器是承認，這個數字是不是一個理性的數目一樣， pi有價證券投資 and does not stretch out to an infinity of decimal places with no apparent pattern.和不舒展，以一個無限的小數位沒有明顯的模式。 Instead 2/86400 is a rational number that could be converted into a fraction (It is 2/86400 or 1/43200).而不是2 / 86400是一個理性的數目，可轉化為一小部分（ 2 / 86400或1 / 43200 ） 。 After the first decimal place (which is a “3″) the 148″ repeats ad infinitum .後的第一小數位（這是一個“ 3 ” ） 148 “ 無限重複的廣告 。

So, why does this calculation show up when you type in the TV show name “Two a Days”.那麼，為何這是否計算表明，當您鍵入的電視節目名稱為“兩個1天” 。 It’s either a joke, or more likely Google’s calculator algorithm spots the units of days, sees a number next to it and the letter “a” and assumes you want an answer.它的要么是一個笑話，或更可能是Google的計算器算法點的單位內，看到了一些它旁邊的和字母“ A ”和假設您想要一個答案。 Try it with “three a week” and you will also get an answer “4.96031746 × 10-6 hertz”.嘗試它與“三個有一個星期” ，你也將獲得一個答案“ 4.96031746 ã - 10-6赫茲” 。 “100 an hour = 0.0277777778 hertz”, you get the picture. “ 100 1小時= 0.0277777778赫茲” ，您就獲得了圖片。 Similarly, type in “pound a kilogram” and you get a conversion factor: “1 pound a kilogram = 0.45359237″ and vice versa “1 kilogram a pound = 2.20462262″ and so on.同樣地，類型，在“磅一公斤”和你得到的換算係數： “一磅一公斤= 0.45359237 ”反之亦然“ 1公斤1英鎊= 2.20462262 ” ，等等。 All answers are given to far too many significant figures to be practical in most measurements, for most everyday uses.所有答案都給予太多顯著的數字，實際在大多數的測量，對於大多數日常用途。 I kg is 2.2 lbs, but we have discussed those issues endlessly elsewhere on this site in our i公斤，是2.2磅，但我們已討論了這些問題，不斷在其他地方關於這個站點在我們的 how to work out significant figures如何工作的重大數字 section.一節。 For now it is interesting just to know how much math there is in popular TV.現在有趣的是，只是為了知道有多少數學有受歡迎的電視。
