Charge density units
Note the units for surface charge density will be charge/area (e.g. C/m2). Line Charge Density Finally, we also consider the case where charge is unevenly distributed across some contour C. We can therefore define a line charge density as the charge ∆Q along a small distance ∆A, located at point r of contour C. C ∆A rMathematical symbols use a roman, serif font (½, +, √, cos) — except when they are applied to calculations with units. Units are written with a roman, sans-serif font (m, N, ℃) as are mathematical operations with numbers and units (7 kg × 10 m/s ÷ 3 s = 23.3 N).
