Jin to KG Converter (斤 to kg)

Jin weight conversion chart

Use kilograms = jin ÷ 2. For pounds, divide that kilogram value by 0.45359237. Select a value in the first column to load it into the tool. Table results in pounds are rounded to four decimals.

How to use the result

A listing marked 建议体重 90–110斤 recommends a body weight of 45–55 kg. Enter 90–110 above to convert both endpoints at once. This is a weight range, not a guarantee that the garment will fit; compare chest, waist and garment measurements too.

Is one jin the same as one pound?

No. A modern mainland jin is exactly 0.5 kg; an international avoirdupois pound is exactly 0.45359237 kg. One mainland jin is approximately 1.102311 lb.

Why does the last decimal change?

The tool calculates using the full unit factors and rounds the displayed answer to at most six decimal places. Very small values use scientific notation. Swapping uses the calculated value rather than a rounded display string; copying includes the unit and the method.

Method and sources

Taizhou government unit table supports the mainland 500 g jin. The pound factor follows NIST SP 811, Appendix B, note 22 (PDF). The word catty alone is region-dependent: confirm the seller’s location before using a conversion.

Weight and unit-price conversions go in opposite directions

To turn weight into kilograms, multiply jin by 0.5. To turn a price per jin into a price per kilogram, multiply the unit price by 2. Total cost is unit price × quantity in the same unit. This module does not apply discounts, delivery charges or currency conversion.
