Strength to Weight & Modulus to Weight

[CRich]

Homework Statement

σ=230MPa (tensile strength)
E=15GPa (modulus)
ρ=1.85 g/cm^3 (density)

Homework Equations

Strength/Weight = σ/ρ
Modulus/Weight = E/ρ

The Attempt at a Solution

Strength/Weight = σ/ρ = 230x10⁶ N/m² / 1850 kg/m²
= 124324.32 (Units?) ___Shouldn't this be unit less?

Modulus/Weight = E/ρ = 1.5x10 ¹⁰ N/m² / 1850 kg/m²
= 8108108.108 (Units?) ___Shouldn't this be unit less?

____Any help is appreciated, thank you__

Units are Nm/kg using mass density. Or if you use weight density,
the
units are length units (meters or feet or inches, etc)
