Hello,

I know how to get the mean, median… about @benchmark, nonetheless, those values are given in the suitable unit (ms, µs, ns) but I need to know with Julia what is this unit. Or, else, set the unit to “second”.

I have to do lot of tests and executions times must be homogenous.

Thanks

The unit of measure is `ns` when you inspect the `times` vector inside the result of `@benchmark`:

```julia
julia> using BenchmarkTools

julia> b = @benchmark rand(10000)
BenchmarkTools.Trial: 10000 samples with 1 evaluation.
 Range (min … max): 8.800 μs … 3.340 ms ┊ GC (min … max): 0.00% … 98.78%
 Time (median): 9.800 μs ┊ GC (median): 0.00%
 Time (mean ± σ): 20.111 μs ± 61.081 μs ┊ GC (mean ± σ): 11.34% ± 3.98%
