Which statement is true according to the material?

• A. Fahrenheit to Celsius uses F = 9/5 (C+32)
• B. Celsius to Fahrenheit uses F = 9/5 (C+32)
• C. 1 kg equals 1000 g
• D. 1 tsp equals 10 mL

Answer: (C)

Mass and volume use standard metric relationships, and one clear truth is that a kilogram equals 1000 grams because the prefix kilo means a thousand. This is a fundamental rule in the metric system, so 1 kg is 1000 g. The other statements mix up common conversions. For temperature, the correct Celsius-to-Fahrenheit formula is F = (9/5)C + 32, not F = 9/5(C+32). The teaspoon-to-milliliter relationship is about 5 mL per teaspoon, not 10 mL, so that statement isn’t accurate.
