Frequently Asked Questions

What is the difference between mass and weight?
Mass is the amount of matter in an object (measured in kilograms, grams, etc.), while weight is the force exerted on that mass by gravity (measured in newtons, pound-force, etc.). Our converter handles both types of measurements.

How accurate are the weight conversions?
Our tool uses precise conversion factors with high decimal precision. For scientific and specialized units, we use established scientific constants and conversion factors.

What is the difference between a metric ton and a short ton?
A metric ton (tonne) equals 1000 kilograms, while a short ton (US ton) equals 2000 pounds (approximately 907.185 kilograms). A long ton (UK ton) equals 2240 pounds (approximately 1016.05 kilograms).

Can I convert traditional weight units like tola and maund?
Yes, our tool includes various traditional and regional weight units from different cultures, including Indian, Pakistani, Bangladeshi, and other regional trade measurements.

Is my data kept private when I use this tool?
Absolutely. All conversions happen locally in your browser. We don't store any of your input data or conversion results on our servers.
