MIPS are a measure of the processing power of a CPU. The number of MIPS is dependant on the CPU installed. Please ask one of your sysprogs or capacity / performance people for this site specific information.
However, if this is not what you want, please ask clearly.

One of my friend gave me the formual as
491*(CPU Time/(Elapsed Time*3))
Is that correct ?
Since you don't provide us with any details such as the machine you're running on, the model number of the machine, whether or not the LPAR is capped, whether or not your job is running while the LPAR is capped, we could not possibly provide a yes answer. However, since MIPS was an IBM measurement (no longer supported by IBM, by the way) of the entire processing workload (including I/O to disk, I/O to tape, channel usage, memory usage, paging, cycle consumption, and so forth) of a machine and was absolutely never applied to individual jobs, we can categorically state that your formula is wrong. There is no way to calculate a MIPS number for an individual job, period. It is wrong to talk about MIPS for a job.
Research on IBM's web sites the concept of MSU and learn to use it.

Service Units per job is another measurement. Each processor type and capacity has a "Services Units per second" value. Multiply the SU/sec value times the CPU seconds used by the job to get the total SUs.
Faster processors have a larger SU/sec value so jobs ending more quickly have a similar total SUs number to the same job on a slower CPU. This gives a rough comparison of workloads on various machines, assuming the resources (CPU, I/O and memory) are weighted the same on each machine.
