ConvertAll: Weight & Shipping

Convert kg and lb, estimate shipping weight, and reuse saved inputs offline.

Handle everyday weight conversions and repeat parcel calculations in one place. Results update as you type. Copy a result or reopen a recent conversion.

Weight and unit conversion
• Convert kg, g, lb, oz and other supported weight units
• 18 categories and 179 units, including length, area, volume and temperature
• Search categories and units, save favorite pairs and revisit recent conversions
• Decimal and grouping interpretation follows the app language, with adjustable result precision

Repeat shipping calculations
• Calculate dimensional weight from box dimensions, actual weight and your divisor
• Switch between cm/kg and in/lb while preserving the physical meaning of your divisor
• Reuse the last dimensions, weight, unit system and divisor saved on your device
• Start quickly with standard box presets
Shipping results are estimates based on your inputs. The app does not quote carrier prices or provide a final billed weight with carrier rounding and surcharges. Check your carrier's divisor and rules.

Tools for related tasks
• Kitchen: convert weight and volume using ingredient density or your own density. This tool uses a 240 mL cup; results are approximate.
• Barbell: calculate symmetric plate combinations from your available plates and bar weight
• Weight log: keep entries and a goal on your device. This is not a medical diagnostic tool.
• Calculator, BMI, tip and date tools
BMI categories are general adult reference values, not an assessment for children or adolescents, diagnosis or treatment. Consult a qualified healthcare professional for health decisions.
Kitchen settings and barbell inventory are also saved locally.

Core calculations work offline. The current app has no in-app ads or purchases and requires no account. It supports 28 app languages and light and dark themes.

Requires Android 10 or later. Inputs and records are stored on your device; the app provides no account or cloud sync. Recovery after uninstalling or changing devices is not guaranteed. Operating-system device backups follow your device settings. Copying and sharing selected results uses operating-system features.
