# Talk:Metric system


### Metric system
Why is kilogram considered a base unit; not gram? And why is that not described in this article? Stevebroshar (talk) 11:55, 26 December 2024 (UTC)

This is described in SI base unit, linked via a hatnote at the section "SI base units" of the article International System of Units, which is linked at the top of this article: Though the rules governing the metric system have changed over time, the modern definition, the International System of Units (SI), defines the metric prefixes and seven base units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd). —⁠andrybak (talk) 22:09, 20 October 2025 (UTC)

WRT "The decimalised system is based on the metre". That implies that metric/SI system is based on the meter. But, it's not. I don't understand the intent of this sentence. Stevebroshar (talk) 11:58, 26 December 2024 (UTC)
