Engineering & CS Workbench
Engineering calculators for computer science, electronics, software, and applied math.
The Logic Gate brings together interactive tools for circuits, systems, software, signals, math, and everyday technical problem solving. Each calculator pairs fast inputs with clear formulas, assumptions, and reference context for students, designers, developers, and engineers who need quick checks without losing the underlying reasoning.
The library covers digital logic and computer architecture, electronics and PCB design, signal processing, networking, programming utilities, mechanical engineering, civil engineering, fluids, physics, and applied mathematics. It is built around practical engineering workflows such as sizing resistors, checking timing margins, estimating trace width, converting binary values, formatting data, and validating numerical results.
Featured engineering calculators
Popular tools focus on repeat engineering calculations where a small error can waste lab time: floating-point encoding, Karnaugh map simplification, PCB trace sizing, UART timing, and number-base conversion.
IEEE-754 Visualizer
Inspect sign, exponent, mantissa, bias, and hidden-bit behavior for 32-bit floating point values.
4-Variable K-Map Solver
Click through a Gray-code K-map and generate a simplified SOP expression with don't-care support.
PCB Trace Width Calculator
Estimate external copper trace width from IPC-2221 current, copper weight, and temperature rise inputs.
UART Baud Rate Calculator
Calculate integer dividers, achieved baud rate, and serial timing error from an oscillator clock.
Hex / Binary / Decimal / Base64
Live-synchronized number-system conversion for embedded debugging and packet inspection.
Technical tool categories
The Logic Gate organizes calculators by engineering discipline so related formulas, converters, and reference tables stay close together. Categories include circuit design, computer architecture, signal processing, software utilities, mechanical systems, civil calculations, and math references for engineering analysis.
