Hit Ratio Formula
The following formula is used to calculate the Hit Ratio.
HITR = H / (H+M) * 100
- Where HITR is the Hit Ratio (%)
- H is the total number of cache hits
- M is the total number of cache misses
To calculate a hit ratio, divide the number of hits by the sum of the number of hits and misses, then multiply by 100.
How to Calculate Hit Ratio?
The following example problems outline how to calculate Hit Ratio.
Example Problem #1:
- First, determine the total number of cache hits.
- The total number of cache hits is given as: 30.
- Next, determine the total number of cache misses.
- The total number of cache misses is provided as: 15.
- Finally, calculate the Hit Ratio using the equation above:
HITR = #H / (#H+#M) * 100
The values given above are inserted into the equation below and the solution is calculated:
HITR =30 / (30+15) * 100 = 66.667 (%)
Example Problem #2:
For this problem, the variables required are provided below:
total number of cache hits = 160
total number of cache misses = 14
Test your knowledge using the equation and check your answer with the calculator above.
HITR = #H / (#H+#M) * 100 = ?
