Units & Measurements · Engineering Unit Abbreviations

The SI unit of speed, used in physics, engineering, meteorology and athletics. Many European forecasts give wind speed in m/s, and the speed of sound in air is about 343 m/s at 20°C.

Example: Gusts reached 28 m/s along the coast, equivalent to about 100 km/h.

Multiply m/s by 3.6 for km/h or by about 2.237 for mph. Usain Bolt's peak speed during his 2009 world-record 100 m was about 12.4 m/s. Acceleration uses m/s², with standard gravity defined as 9.80665 m/s².

2. Messrs. (used before a firm's name) (M/s)

Writing & Everyday · Title and Honorific Abbreviations

Precedes the name of a business firm in Indian, Pakistani, Bangladeshi and Sri Lankan commercial and official correspondence, as in "M/s Sharma Traders." It derives from Messrs. but is applied to any company.

Example: The tender was awarded to M/s Kapoor Constructions Pvt. Ltd. for the bridge repairs.

Readers elsewhere sometimes take M/s for "Ms." or "Mrs.," but in South Asian usage it is a formal marker for a firm, partnership or company, found on invoices, government tenders and court documents. It is written with a slash and no period. International business English generally omits it.
