About This Tool
The DPI Converter analyzes the relationship between image density and physical size. It converts values between DPI and DPCM using the exact factor 2.54 cm per inch. Example: 300 dpi equals 118.11 dpcm, enabling precise planning for print assets and web images.
Conceptually, density is a unit mapping validated by straightforward arithmetic. The tool applies bidirectional formulas with consistent rounding rules and deterministic results. It does not rely on external data; calculations are computed locally for reproducibility.
Who benefits include graphic designers, print houses, QA teams, and developers integrating asset pipelines. Its unique value lies in strict input validation, clear numeric outputs, and optional batch processing. Typical use cases include estimating print size from pixels and validating client specifications.
How to Use
1. Provide inputs: value, from_unit, to_unit.
2. Validate inputs: ensure positive numbers and supported units.
3. Run calculation: the tool applies the bidirectional formula.
4. Review outputs: read the result, formatted to two decimals.
5. Optional: export results in batch mode for multiple rows.
