Google Search Does Bit Rate Calculations

[Soopafresh]

Enter the following in the search field -

(4.38 GB) / (93 minutes)

Noob: "How do I get X amount on a disc?"

Reg: Do a Google Search!

[hhhhbk]

you dont even need the brackets

and it doesnt matter whether or not you have a space between the magnitude and the unit

all that does matter is that you have the correct capitals and lower case

MB is megabytes
Mb is Megabits
mb is millibars

Must be for avi.

How about mpeg2

The answer is in k BYTES per second. Multiply by 8 to get k BITS per second.

[waheed]

Cool. Never knew google was capable of that. Thanks for the info.

[SLK001]

But it's not even close to being correct. By MY calculations,

4.38GB / 93 Minutes = 6.279Mbps

or

(4.38GB * 8b/B) / (93Min * 60sec/Min)

[SLK001]

Or, in kBps the answer should be 784,946 kBps.

[Raga]

You can also type:

4.38 GB / 93 minutes in kbps

And you get:

(4.38 GB) / (93 minutes) = 6 584.60628 kbps

So no need to multiply by eight.

Should point out that for video 1 kbps is 1,000 not 1,024.

[lordsmurf]

After a while, calculations are not needed.
You can guesstimate in your head and usually come to within 100MB.

This is so confusing, can someone tell me why the difference.

Because marketers thought they would make storage sound more attractive and larger using a base 10 counting system, and showed scant regard (and an extreme lack of computer nous) for the traditional base 2 counting system that most of us are familiar with when using PCs. Unfortunately in their quest to make software more noob-friendly, software developers started to also deal in these terms that so many noobs were familiar with, having read them off the top of their DVDR spindles and so forth. And so you get the snowball effect just to remain competitive in the market, despite the information actually being incorrect in the first place

Digital computers deal in powers of 2. In the early days of computers engineers referred to 1024 (2 to the 10th power) bytes of memory as 1 Kilobyte. Following this rule, 1 megabyte is 1024 x 1024 bytes, 1 gigabyte is 1024 x 1024 x 1024 bytes.

Outside of computers, like when measuring distances in meters, 1 kilometer is 1000 meters, 1 megameter is 1000 x 1000 meters, and 1 gigameter is 1000 x 1000 x 1000 meters.

Well marketers caught on to this and decided they could label products in non-computer K rather than computer K to make them sound bigger. So a hard drive that could hold 1 computer GByte (1,073,741,824 bytes) started being sold as as 1.07 GB. People who didn't know better would assume a drive labeled 1.07 GB was bigger than another labeled 1 GB even though they may have been exactly the same size. Of course, once one manufacturer did this all the others followed. (I don't mean to imply that hard drive manufacturers started this misleading advertising with 1 GB drives, I'm just using it as an example.)

DVD media labeled as 4.7 GB holds about 4,700,000,000 bytes. If you use computing G rather than non-computing G that's only ~4.38 GB.
