Understanding Unit Systems
The world primarily uses two systems of measurement: the Metric System (SI) used by most countries, and the Imperial/US Customary System used mainly in the United States, Liberia, and Myanmar.
The metric system is based on powers of 10, making conversions straightforward (1 km = 1,000 m). The imperial system uses various conversion factors that must be memorized (1 mile = 5,280 feet). Our converter handles all the math for you.
Frequently Asked Questions
How accurate are these conversions?
Our conversions use standard conversion factors and are accurate to at least 6 decimal places. For scientific work requiring extreme precision, please verify with specialized tools.
What's the difference between US and Imperial measurements?
US and Imperial systems differ mainly in volume measurements. A US gallon is about 3.79 liters, while an Imperial gallon is about 4.55 liters. Our calculator uses US measurements by default.
Why do temperature conversions work differently?
Temperature scales have different zero points and intervals. Celsius and Fahrenheit use offset conversion formulas (°F = °C × 9/5 + 32), while Kelvin is an absolute scale starting at absolute zero.
What is a metric ton vs US ton?
A metric ton (tonne) equals 1,000 kg (2,204.6 lbs). A US ton (short ton) equals 2,000 lbs (907.2 kg). An Imperial ton (long ton) equals 2,240 lbs (1,016 kg).
How do I convert cooking measurements?
Use our Volume category for cooking conversions. Common conversions: 1 cup = 16 tablespoons = 48 teaspoons = 236.6 ml. For weight-based recipes, 1 cup of flour ≈ 125g, 1 cup of sugar ≈ 200g.
What's the difference between KB and KiB?
KB (kilobyte) traditionally means 1,024 bytes in computing, while SI defines it as 1,000 bytes. KiB (kibibyte) explicitly means 1,024 bytes. Our calculator uses the binary (1,024) standard common in computing.
