How to Calculate Technology
What is Technology?
Technology calculators cover computing and digital tools: network subnets, binary/hex conversion, screen resolution (PPI), data storage units, download times, and password entropy.
Formula
- PPI
- √(W²+H²) / Screen diagonal inches — √(W²+H²) / Screen diagonal inches
Step-by-Step Guide
- 1Binary: base 2 (0s and 1s); Hex: base 16 (0–F)
- 2PPI = √(W²+H²) / Screen diagonal inches
- 3Data: 1 GB = 1,024 MB = 1,048,576 KB
- 4Download time = File size (bits) / Bandwidth (bits/sec)
