USCS to SI Unit Conversions

The following table provides common conversion factors between United States Customary System (USCS) units and their SI equivalents:

Key Definition

Kip: A unit of force equal to $1000 \text{ lb}$ (pounds-force), commonly used in structural engineering. The name is a portmanteau of "kilo" and "pound."

Usage Notes

• To convert from USCS to SI: $\text{SI value} = \text{USCS value} \times \text{conversion factor}$
• To convert from SI to USCS: $\text{USCS value} = \text{SI value} \div \text{conversion factor}$

For example, to convert $100 \text{ psi}$ to kPa:

$100 \text{ psi} \times 6.894 = 689.4 \text{ kPa}$
