Viss vs. Kilogram: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 10, 2023
A viss is a traditional Burmese unit of weight equal to about 1.63 kilograms, while a kilogram is a standard metric unit of mass equal to 1,000 grams.

Key Differences

Viss is a unit of weight used predominantly in Myanmar (Burma), equivalent to approximately 1.63 kilograms or 3.6 pounds. Kilogram, on the other hand, is a unit of mass in the International System of Units (SI), equal to 1,000 grams, and widely used globally.
The viss is deeply rooted in traditional Burmese commerce and daily life, often used for measuring produce and goods in local markets. In contrast, the kilogram is a fundamental unit in international science, trade, and industry, recognized and utilized worldwide.
While the viss reflects regional and cultural measurement practices, its use is limited outside of Myanmar. The kilogram, however, is part of a standardized global measurement system, ensuring consistency and accuracy in mass measurement across different countries and fields.
The value of a viss can vary slightly based on regional or local standards within Myanmar. The kilogram, standardized under the SI system, maintains a fixed value defined by the Planck constant, ensuring uniformity in measurement.
In modern commerce and science, the viss is less commonly used compared to the kilogram, which is integral to international standards in numerous fields including science, engineering, and global trade.

Abbr. kg The base unit of mass in the International System, equal to 1,000 grams (2.2046 pounds). See Table at measurement.


Kilogram force.


In the International System of Units, the base unit of mass; conceived of as the mass of one litre of water, but now defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10-34 when expressed in units of kg⋅m2⋅s−1. Symbol: kg


(proscribed) The unit of weight such that a one-kilogram mass is also a one-kilogram weight.


A measure of weight, being a thousand grams, equal to 2.2046226 pounds avoirdupois (15,432.34 grains). It is equal to the weight of a cubic decimeter of distilled water at the temperature of maximum density, or 39° Fahrenheit.
