• 1 ms, millisecond, a small measure of time ("m" for milli, meaning 10⁻³ = 1/1000 multiplier).
• 1 Ms, megasecond, a large measure of time ("M" for mega, meaning 10⁶ = 1 000 000 multiplier).
• 1 mS, millisiemens, a small measure of electric conductance.
• 1 MS, megasiemens, a large measure of electric conductance.

 

(FYI: one siemens is equal to the reciprocal of one ohm (Ω⁻¹) and is also referred to as the mho)
