FAQ

Does it support Taiwanese units?

Yes. Weight includes catty (台斤 = 0.6kg, market use), area includes ping (坪 ≈ 3.30579m², housing use) — plus 5 more categories.

How does temperature work?

Formula-based, not proportional: °F = °C × 9/5 + 32 (25°C = 77°F); Kelvin = °C + 273.15.

Can I see all units at once?

Tap "All Units" to see the full table for the current category; tap any cell to make it the target.

Is it offline?

Yes. All factors are bundled; conversion is pure frontend and works offline.

1024 or 1000 for data size?

Binary 1024 (1KB = 1024B), matching OS displays; drive makers label in 1000-based — that's the gap.

Quick mental math for miles/feet?

1 mile ≈ 1.6km, 1 foot ≈ 30.5cm, 1 inch ≈ 2.54cm for magnitude; exact values here.
