Exact place values
1 wan (万 / 萬) is 10,000; 1 yi (亿 / 億) is 100,000,000. 10,000 wan equals 1 yi. The word billion here means 1,000,000,000, so 1 billion = 10 yi. Enter decimals, correctly grouped commas, or a simple suffix such as 1.2万. Compound expressions and written Chinese numerals are not parsed; enter their numeric components separately.
Precision and examples
1.25 wan = 12,500. 2.5 yi = 250,000,000 = 250 million. Very large values use decimal strings instead of floating-point arithmetic, up to 60 input characters. This is place-value conversion, not an exchange rate or a financial product.
