SUMMARY
The correct units for resistivity (p) in the equation R = pl/A are derived from the rearrangement of the formula to p = AR/l. Given that resistance (R) is measured in ohms (Ω), which is equivalent to m²kgS⁻³A⁻², the units for resistivity are confirmed to be m³kgS⁻³A⁻² or ohm-metre (Ω·m). This conclusion is supported by the calculations presented in the discussion.
