Data compression calculator

How is the compression ratio calculated?
Compression Ratio is the total volume of the engine divided by the clearance volume of the engine..
What does data compression involve?
Data compression is a reduction in the number of bits needed to represent data.
Compressing data can save storage capacity, speed up file transfer and decrease costs for storage hardware and network bandwidth..
What is the algorithm for data compression?
The Lempel–Ziv (LZ) compression methods are among the most popular algorithms for lossless storage.
DEFLATE is a variation on LZ optimized for decompression speed and compression ratio, but compression can be slow..
In short, compression ratio is defined as adding the swept and clearance volumes together before dividing that by the clearance volume alone: (Swept Volume + Clearance Volume) Clearance Volume.
We'll walk you through the math and how to find the variables needed to calculate compression.

Calculate data compression rate or data size before and after compression. Enter two of the three values at size and ratio and click Calculate.
