1. The problem is to convert 830 milliliters (ml) to centiliters (cl). 2. We use the conversion factor: 1 cl = 10 ml. 3. To convert ml to cl, divide the number of milliliters by 10. 4. Calculation: $$830 \text{ ml} = \frac{830}{10} \text{ cl}$$ 5. Simplify the fraction: $$830 \div 10 = 83$$ 6. Therefore, $$830 \text{ ml} = 83 \text{ cl}$$ 7. The answer is 83 centiliters.
