## What is US Units Guide?

US Units Guide helps metric-system users understand US customary measurements in everyday American life.

Use it when you see Fahrenheit weather, feet and inches, pounds, miles, gallons, MPG, tire pressure, grocery prices, fuel prices, housing area, US recipes, or parcel weights.

Core tools:
- Weather: Fahrenheit and Celsius
- Height and weight: ft/in, cm, lb, kg
- Distance, speed, fuel economy, tire pressure, and fuel price
- Home area, grocery price, kitchen volume, and parcel weight
- Reverse conversion when you need to go from metric back to US units

The app is built for practical daily use, not a giant scientific unit encyclopedia. Your language, region, history, text size, appearance, and exchange-rate choices are stored on your device. No account is required, and this version does not include third-party advertising or cross-app tracking.
