Latency Numbers Every Programmer Should Know

2025 Update - Interactive visualization of computer latency at different scales. Hover over metrics to see data sources.

View Scale:

Nanoseconds (ns) - < 1 μs

Microseconds (μs) - < 1 ms

Milliseconds (ms) - > 1 ms

Note: The colored bars show relative speed. Watch how they change with different scales!

1 second = 1,000 milliseconds = 1,000,000 microseconds = 1,000,000,000 nanoseconds
