Weights and measures

Does Japan follow the usual kilogram/gram measure or is it the pound that is popular?
Thank you.

centimeters/kilogram measurement
never been used inch/pound/stone measurement

In Japan, pound or feet are rarely used.
Only few imports, I think?

BTW, few traditional measures are used even today.
For example, 畳(jou) for Japanese room, 升(show) for Japanese sake.

Yes, and also, like in most of the world, the temperature is in Celcius degrees.

The Japanese, like a majority of countries, use the metric system.

from Wikipedia:
"The metric system is an internationally agreed decimal system of measurement that was originally based on the mètre des Archives and the kilogramme des Archives introduced by France in 1799.
Over the years, the definitions of the metre and kilogram have been refined and the metric system has been extended to incorporate many more units....
...the term is now often used as a synonym for "SI"or the "International System of Units"―the official system of measurement in almost every country in the world....

The basic units are the meter for length, the kilogram for mass, the liter for liquids.
A liter of water weight 1 kilogram and is contained in a cube 10cm X 10cm X 10 cm.

Surfaces are measured in square meter for relatively small areas, like rooms.
In the metric system, multiples and sub-multiples of units follow a decimal pattern i.e 10, 100, 1000 bigger or smaller..
Their name indicate the multiples or sub-multiples.
