💡 Conversion Tips

🌍 Metric vs Imperial: Most countries use the metric system (meters, kilograms), while the United States, Myanmar, and Liberia primarily use the imperial system (miles, pounds). Knowing the local unit system before traveling helps with everyday communication.

🏠 HK & Macau Area: Real estate in Hong Kong and Macau is priced in square feet (ft²). 1 sq ft ≈ 0.093 m². Taiwan commonly uses "ping", where 1 ping ≈ 3.3 m² ≈ 35.6 sq ft.

⚖️ Taiwan vs HK Weight Units: Taiwanese catty = 600g, Taiwanese tael = 37.5g; HK catty ≈ 604.8g, HK tael ≈ 37.8g. The difference is small but worth noting when trading in traditional markets.

🌡️ Temperature Reading: The US uses Fahrenheit (°F); most other countries use Celsius (°C). Quick mental estimate: °F ≈ °C × 2 + 30.

⚡ Electricity Billing: Electricity in Taiwan and Hong Kong/Macau is billed in kilowatt-hours (kWh). 1 kWh = 1,000 watt-hours = 3,600 kilojoules. Knowing your appliance's wattage helps estimate electricity costs.

⛽ Fuel Efficiency Conversion: Taiwan uses km/L, the US uses MPG (miles per gallon), and Europe uses L/100km. Check the local measurement method before refueling.
