Your specific task is calculate pwm duty cycle from on-time and period. Open the page, drop your input, get the result — typically under a second.
Your goal is calculate inductive and capacitive reactance at a given frequency. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. PWM Duty focuses on calculate pwm duty cycle from on-time and period; Reactance focuses on calculate inductive and capacitive reactance at a given frequency. Try whichever description matches your goal more closely — they're both free.
Yes — both tools are free for unlimited personal use. The Pro plan unlocks higher limits and batch features but the core functionality stays free forever.
Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
No. Both PWM Duty and Reactance work without signup. We only ask for an email if you decide to subscribe to a paid plan.
