The Ultimate Unit Conversion Guide: Length, Weight, Temp & Storage

1. The Metric System (SI) vs. Imperial System

Global commerce, science, and everyday life require translating measurements between the decimal International System of Units (Metric) and the Imperial / US Customary system.

2. Length & Distance Conversion Factors

• 1 inch = 2.54 cm (Exact)
• 1 foot = 12 inches = 0.3048 m
• 1 meter ≈ 3.28084 feet = 39.3701 inches
• 1 mile = 1.60934 kilometers = 5,280 feet

3. Weight & Mass Conversion Factors

• 1 kilogram = 2.20462 pounds (lbs)
• 1 pound = 16 ounces = 453.592 grams
• 1 stone (UK) = 14 pounds = 6.35029 kg

4. Digital Storage: Powers of 2 vs Powers of 10

In telecommunications and marketing, 1 Kilobyte (KB) is 1,000 bytes. In computer operating systems, 1 Kibibyte (KiB) is 1,024 bytes (2¹⁰). CalcWillow's converter supports binary and decimal digital storage conversions across bits, bytes, KB, MB, GB, and TB.
