Why Multiply by 10 in Dead Load Calculations?

[PhysicsApprentice]

density = 1000
volume = 0.6 x 0.020 x 1.0
answer = 0.6 x 0.020 x 1000 x 10 = 120N/m

can someone please explain to me why you have to times it by 10 at the end to get 120n/m

i understand the equation just don't understand the x 10 part at the end.

Try writing down the units as well. You may see the answer easier. And also take into consideration that g is often given as 10m/s^2.

The x 10 at the end is used to convert the units from Newtons (N) to Newtons per meter (N/m). This is necessary because density is typically measured in kilograms per cubic meter (kg/m^3), so by multiplying the density by the volume, the units would be kg/m^3 x m^3, which simplifies to kg. However, when calculating dead loads, we are interested in the force per unit length (N/m), so we need to convert the units to Newtons per meter by multiplying by 10, which is the acceleration due to gravity (g = 10 m/s^2). This conversion is necessary to ensure that the units are consistent and the final answer represents the correct force per unit length.
