Study the data table below, which shows the annual electronic waste (e-waste) generated in millions of tonnes for the Americas and Asia between 2010 and 2025.
| Year | 2010 | 2013 | 2016 | 2019 | 2022 | 2025 (Projected) |
|---|---|---|---|---|---|---|
| Americas | 11.5 | 12.1 | 13.4 | 14.2 | 14.9 | 15.4 |
| Asia | 15.8 | 18.4 | 24.1 | 27.5 | 31.2 |
The e-waste generated in Asia in 2016 was 21 180 000 000 kg21\,180\,000\,000\text{ kg}21180000000 kg.
Given that 1 metric tonne = 1000 kg, convert this value into millions of tonnes to one decimal place and complete the data table.
