What is the specific weight of water in metric units?

• A. 9.8 n/m^3
• B. 62.4 lb/ft^3
• C. 1000 kg/m^3
• D. 14.7 psi

Answer: (A)

The specific weight of water in metric units is commonly expressed as 9.81 kN/m³ or approximately 10 kN/m³ when rounded for simplicity in engineering contexts. However, the option that best represents the specific weight of water in metric units here is 1000 kg/m³. To clarify, specific weight is defined as the weight of a unit volume of material. In the case of water, at standard conditions, the density is approximately 1000 kg/m³. The specific weight can also be calculated using the equation: Specific Weight = Density × Acceleration due to gravity Given that the acceleration due to gravity is approximately 9.81 m/s², when you multiply 1000 kg/m³ by 9.81 m/s², you arrive at a specific weight of about 9810 N/m³, or roughly 9.81 kN/m³, validating that water's specific weight in a context involving metric units is indeed rooted in the density of water. Other options reflect either incorrect units or values that do not pertain to the metric system specifically regarding specific weight. Thus, when discussing the specific weight of water in metric terms, the correct value is directly linked to the density of
