亿立方米
How to Understand
亿立方米 is a unit of volume commonly used in China to measure large quantities of water, gas, or other substances. It represents 100 million cubic meters, which is equivalent to 10^8 m³. This term is often used in contexts related to natural resources, energy, and environmental planning.
The character 亿 (yì) means 'hundred million,' lì (立) means 'to stand' or 'to be established,' fāng (方) means 'square' or 'cubic,' and mǐ (米) means 'meter.' Together, they form a compound noun that literally translates to 'hundred million cubic meters.'
