Thermal Expansion focuses on thermal expansion table — formula, units, worked example; 3-Phase Pwr focuses on calculate three-phase power from line voltage, current, and power factor. 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.
