| Key features | - Editable assumptions based on actual product labels
- Visible net quantity, waste, and package rounding
- Field guides for project measurement and material planning
- Support for US and metric measurements
| - Resistor Color Code: read 4, 5 and 6-band resistors or find bands for a value
- LED Resistor: pick the current-limiting resistor and power rating
- Voltage Divider: output voltage, loading effect, or solve R2 for target Vout
- RC Filter: cutoff frequency, time constant and attenuation at any frequency
- LC Resonance: resonant frequency, characteristic impedance and Q
- 555 Timer: astable frequency/duty cycle and monostable pulse width
- Battery Life: runtime from capacity, active/sleep current and duty cycle
- PCB Trace Width: IPC-2221 trace width for current and temperature rise
- Electronics Unit Converter: SI prefixes, AWG to mm², mil to mm, dBm to mW, oz copper

| What makes it different | - Shows net quantity, waste allowance, and packaging rounding visibly together for easy comparison with product labels
- No account, sales call, or hidden formula required
- Fifty practical free calculators covering six major project categories
- Editable product-specific assumptions rather than fixed formulas
- Separate calculators for similar materials with different inputs and purchase results
| - Real E-series resistor values, not ideal numbers
- Engineering notation input and result sharing as links
- No ads, no tracking, no sign-up for free calculators
- Whole-device BOM costing and battery-life summary in Pro
- Works on phone at the bench
