  66The Planck length formula has correct dimensions:
  67  ℓ_P = √(ℏG/c³)
  68  [ℏG/c³] = [L²T⁻¹M¹][L³T⁻²M⁻¹]/[L³T⁻³M⁰]
  69          = [L⁵T⁻³M⁰]/[L³T⁻³M⁰]
  70          = [L²T⁰M⁰]
  71  [√(ℏG/c³)] = [L¹] ✓
  72
  73The Planck time formula has correct dimensions:
  74  t_P = √(ℏG/c⁵)
  75  [ℏG/c⁵] = [L²T⁻¹M¹][L³T⁻²M⁻¹]/[L⁵T⁻⁵M⁰]
  76          = [L⁵T⁻³M⁰]/[L⁵T⁻⁵M⁰]
  77          = [L⁰T²M⁰]
  78  [√(ℏG/c⁵)] = [T¹] ✓
