For the case you gave, it's easier to convert the mass to length units; the conversion factor is G / c^2, or about 7 x 10^-28 m / kg. So 5 kg/m^3 equates to about 3.5 x 10^-27 m^-2 in curvature units.

Prior to the 1960’s most highway curves in Washington were described by the degree of curvature. Since then, describing a curve in terms of its radius has become the general practice. Degree of curvature is not used when working in metric units. Nomenclature For Circular CurvesCurvature. An important topic related to arc length is curvature. The concept of curvature provides a way to measure how sharply a smooth curve turns. A circle has constant curvature. The smaller the radius of the circle, the greater the curvature. Think of driving down a road. Suppose the road lies on an arc of a large circle.According to the chapter on static equilibrium and elasticity, the stress F / A is given by. F A = YΔL L0, where Y is the Young’s modulus of the material—concrete, in this case. In thermal expansion, ΔL = αL0δT.

A collective term for a series of quantitative characteristics (in terms of numbers, vectors, tensors) describing the degree to which some object (a curve, a surface, a Riemannian space, etc.) deviates in its properties from certain other objects (a straight line, a plane, a Euclidean space, etc.) which are considered to be flat. Remember that the radius is half of the diameter of a circle. You can choose different units of length, depending on the problem or measurement taken. Alternatively, you can enter the circumference of the circular base instead. Enter the height of the cone or the slant height of the cone, depending on which one is known.

Curvature. Curvature measures the rate at which a space curve r(t) changes direction. The direction of curve is given by the unit tangent vector.

The SI unit for activity of a radiative sample is becquerel or Bq, meaning decays per second, which is related to counts per second through the overall detection efficiency. However, in the current SI, it is said that the becquerel has units of s −1, which means that the decay or count in the numerator is dropped.
