2.0 Final Release

Judgement Day

JSR 385 Judgement Day

On Thursday, August 29, 2019 the Final Release of JSR 385 was published by the Java Community Process:

The date coincides with Judgement Day in the Terminator movies.
If a computer system like Skynet ever did become self-aware, hopefully it gets not only its measurement units right. If it ran on Java, then JSR 385 might help ;-)

Corresponding GitHub release tags are:


Zeus in Valhalla


In the "Zeus" hall on JCrete 2019 Hack day Werner got the Valhalla Early-Access Build of Java 14 to run with Unit API.

Bringing together Ancient Greek gods with their equivalents from Nordic mythology if you want. You can find them under valhalla demos.

Public Review Final Approval

This week the first ever Public Review Final Approval Ballot for JSR 385 at the Java Community Process finished. JSR 385 was approved by the JCP Executive Committee:

We plan to release a final Specification document and publish all artifacts to soon. In the meantime, you can find them on Github already, API:
and the TCK:

World Metrology Day 2019

alt text

May 20 is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in 1875. This treaty provides the basis for a coherent measurement system worldwide that underpins scientific discovery and innovation, industrial manufacturing and international trade, as well as the improvement of the quality of life and the protection of the global environment.

World Metrology Day 2019 has a special importance, because on 16 November 2018, the General Conference on Weights and Measures agreed perhaps one of the most significant revisions to the International System of Units (the SI) since its inception. Research into new measurement methods, including those using quantum phenomena, underpin the change, which comes into force on 20 May 2019. The SI is now based on a set of definitions each linked to the laws of physics and have the advantage of being able to embrace further improvements in measurement science and technology to meet the needs of future users for many years to come.

100-Thousandth Download of Unit-API exceeded

Just one week before World Metrology Day 2019 and shortly before the Public Review of JSR 385 the combined downloads of Unit-API (JSR 363 and 385) exceeded the 100-thousandth download within a period of 12 months:
111k Unit-API downloads

See Bintray statistics:
Click "1 Year" date range.

Currently the vast majority are JSR 363 downloads, but once JSR 385 goes Final, we expect to see more of it and probably even a higher total number across both versions.
