About Autocorrect Units
Automatically corrects measurement units as you type; supports SI, imperial, and US customary units.
──────────────────────────────────────────
HOW IT WORKS
Type a measurement into any text box, then press Space or punctuation; it's instantly corrected to the proper format. For example:
𝟱𝗰 → 𝟱 °𝗖
𝟰𝟬,𝟬𝟬𝟬 𝗸𝗺𝘀 → 𝟰𝟬 𝟬𝟬𝟬 𝗸𝗺
──────────────────────────────────────────
WHAT GETS CORRECTED
• Unit symbols — replaced with official notation
• Thousands separators — commas replaced with non-breaking thin spaces, the universal thousands separator
• Number–unit spacing — non-breaking spaces prevent awkward line wraps

GOOD TO KNOW
🔒 Private — your data never leaves your browser.
📋 Accepts units in virtually any variant you can type.
⚠️ Some shortcuts favour common usage over strict SI (e.g. "C" corrects to °C, despite coulombs being valid).
