Title: KH vs MH vs GH
Post by: kevcoin on June 11, 2013, 07:18:17 PM
Can someone pour some clarity on this situation?

When people quote gH/s do they really mean mH/s?

Doesn't the scale go Kilo Mega Giga

IE if I have 2x600 kH/s... that is equal to 1.2 mH/s and not 1200 mH/s

Most of the only calculators ask for your MH/s but say you are expected to make
and average of 0$ a day at 1.2 mH/s and $4.xx if its 1200 mH/s.. when 1200 kH/s gets you $4.xx

You're using some pretty fucked up calculators, friend.

The scale does function the same as how Bytes are measured. KH/MH/GH/TH (KB/MB/GB/TB)

1200KH/s would accumulate practically nothing, 1200MH/s would get you a few dollars-worth per day.

I have two 7950s
They get me around 600 kh/s each without tweaking.

Running both in a pool I get around 5$ a day right now.

600 kh/s x 2 = 1.2 mh/s right?
And not 1200 mh/s

he is referring, when people talk about 1200MH/s =1200Khash/s and this is because they are mining scrypt
sha-256 are in MH
scrypt are in KH

Yes it does go KH/s < MH/s < GH/s < TH/s.

Most CPUs mined in the KH/s range for BTC. GPUs and FPGAs were in the MH/s range. Now, ASICs are measured in the GH/s. Pools and the total network are measured in the TH/s. This is all for BTC, and LTC is different.

Most GPUs will only pull a few hundred KH/s for LTC, compared to a few hundred MH/s for BTC. Lets take a 4x 7950 rig as an example. For BTC, you could get 550MH/s each card, for a total of 2200MH/s, or 2.2GH/s. For LTC, lets say you were getting 600KH/s each card, for a total of 2400KH/s, or 2.4MH/s.

Am I the only one who liked algebra and unit conversions in school? ???

LTC - Kh/s
BTC - Gh/s

Ok that clears it up.

Thanks

Case is important

M=Mega (1,000,000)
m=milli (.001)

To make things confusing kilo (k = 1000) is lowercase, when it would make more sense to be uppercase.

Edit: as defined in the International System of Units

If it helps you to remember, everything below Mega is lowercase.

Topicstarter definitely needs to learn System International (SI) standard prefixes.

Let's do it now:

Exa- = billion billions units  (1,000,000,000,000,000,000 or 10^18)
Peta- = million billions units  (1,000,000,000,000,000 or 10^15)
Tera- = thousand billions units (1,000,000,000,000 or 10^12)
Giga- = billion units (1,000,000,000 or 10^9)
Mega- = million units (1,000,000 or 10^6)
Kilo- = thousand units (1,000 or 10^3)
Gecto- = hundred units (100 or 10^2)
Deca- = ten units (10 or 10^1)

1 - one unit of something (1 the same as 10^0)

deci- = tenth part of unit (1/10 or 10^-1)
centi- = hundredth part of unit (1/100 or 10^-2)
milli- = thousandth part of unit (1/1000 or 10^-3)
micro- = millionth part of unit (1/1,000,000 or 10^-6)
nano- = billionth part of unit (1/1,000,000,000 or 10^-9)
pico- = 10^-12
femto- = 10^-15
atto- = 10^-18

That's all folks!

All you need to know in the modern World of Numbers.

The confusion is probably because it's 1000x slower to mine litecoin than bitcoin.  So in general if your GPU can calculate 600MH/s for bitcoin, it can only calculate 600KH/s for litecoin.  People will assume that you can read their minds and just state a value in KH/s or MH/s without saying which coin.
