Convert Ounce to Kilogram-force square second per meter

The ounce traces its origins to ancient Roman times, where it was based on the uncia, which was 1/12 of a Roman pound (libra). The term "ounce" comes from the Latin "uncia", meaning one-twelfth. In medieval Europe, the ounce evolved as a standardized unit of weight, especially in trade. By the 14th century, the Avoirdupois ounce became the standard for most goods in England, which is equivalent to about 28.35 grams. This measurement was later adopted in the United States and other countries using the imperial system.

This unit originates from engineering contexts where the gravitational metric unit kilogram-force (kgf) was commonly used before the adoption of the SI system. It was part of older metric-based systems in Europe and engineering fields, gradually replaced by the SI unit newton (N) for consistency.
