There is quite a bit of confusion in the industry. In computer science, most people loosely consider 1 Gb as 2^30=1073741824 bytes, while the prefix Giga actually means 10^9, or 1,000,000,000.
When we buy a hard disk, we are told (correctly) that it holds 1 Gb. Manufacturers base it on the mathematical definition of Giga and give you 10^9 bytes (less than 1073741824=1Gibibyte, or 1 GiB). This is standard practice in the disk drive industry. For example, a Windows 7 will show a 3 tera byte external disk as having 2.72 TB, or 3,000,557,891 byes, in which case it is actually assuming a TB to mean 2^40 byes (instead of TiB). That's where confusion lies.
Can something be done about it? Yes, it has been done since 2007. The less well-known, but official quantity for 1073741824 bytes is one GiB, proposed by the International Electrotechnical Commission (IEC), adopted by IEEE, EU, and NIST. Similarly, 1 TiB means 2^40=1,099,511,627,776 bytes. The prefixes have been replaced by bi (for binary), so Kibibyte, Mebibyte, Gibibyte, Tebibyte, etc.are used to represent 2^10, 2^20, 2^30, 2^40 bytes. Unfortunately I have yet to see this widely being used, or even known!
The metric system measures mass in grams or kilograms, distance in meters or kilometers, and volume in liters. It measures temperature in Kelvin or Celsius degrees instead of the Fahrenheit degrees used in the imperial system. The Basic Unit for Mass The metric system measures mass in grams.
If the average person blinks 25 times per minute you have to multiply and times it by 60(which is an hour) to equal {1,500} . Next times the number 1,500 by 24 because that is how many hours are in a day so that would equal {36,000} times a day. Now times 36,000 by 7 because that is how many days of the week so {252,000} is the answer per week.
Now to figure out how many times we blink in a year we will multiply
252,000 by 52 because there are 52 weeks in a year.
