Question

IBM has a computer it calls the Blue Gene/L that can do 136.8 teracalculations per second. How many calculations can it do in a microsecond?
The answer has to be in four significant digits.

Answer 1

There are 1,000,000 micro seconds in one second so multiple 136.8 by 1000000 and you'll get 136,800,000 Tera calculations per second.

Answer 2

IBM has a computer it calls the Blue Gene/L that can do  $136.8* 10^{6}$ calculations in a microsecond or  $136.8$ megacalculations in a microsecond

Further explanation

Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.

There are methods for converting values with multiple units

• Write down your problem.
• Find the conversion for one unit
• Multiply your number by the conversion fraction.
• Cancel out your units.
• Multiply with another conversion fraction the same way.
• Cancel units.
• Repeat until the conversion is done

The seven base quantities and their corresponding units are:

• length (metre)
• mass (kilogram)
• time (second)
• electric current (ampere)
• thermodynamic temperature (kelvin)
• amount of substance (mole)
• luminous intensity (candela)

IBM has a computer it calls the Blue Gene/L that can do 136.8 teracalculations per second. How many calculations can it do in a microsecond?

prefixes : tera = $10^{12}$

micro = $10^-6$, there are  $10^6$  microseconds $\mu s$ in 1 second

$136.8* 10^{12} \frac{calculations}{second} = 136.8* 10^{12} \frac{calculations}{10^6 \mu s}$

So, it can do $136.8* 10^{6}$ calculations in a microsecond or  $136.8$ megacalculations in a microsecond. The answer is in four significant digits
