FAQ
How is pyeong (坪) computed?
1 pyeong ≈ 3.3058 m² (based on the 6-by-6-ja definition). This matches the value used in Korean real estate.
Is KB 1000 or 1024?
This tool uses 1 KB = 1024 bytes (legacy convention common in memory/storage UIs). Telecom/marketing 1 kB = 1000 B (KiB vs KB) may differ — be aware when comparing.
What temperature formulas are used?
°C ↔ °F: F = C × 9/5 + 32. °C ↔ K: K = C + 273.15. Values below absolute zero (~-273.15 °C) are physically meaningless.
How are decimals displayed?
Results adapt precision automatically. Very small numbers switch to scientific notation; normal values show up to 8 significant digits.
Is anything sent to a server?
No. All conversions happen in your browser — the input never leaves the page.
