## System Measurement

Energy and Climate Change Systems of Measurement: * USCS: (formerly the British System) The system used in the U.S. consisting of feet, pounds, and seconds. ?*The Metric System: meters, kilograms, and seconds. ?* Fundamental Units: length, mass, and time. System Length Mass Time SI (mks) Meter Kilogram Second SI(cgs) Centimeter Gram Second USCS (fps) Foot Slug Second Work and Energy System Force = Mass x Acceleration SI (mks) Newton Kg m/s^2 SI (cgs) Dyne Gram Cm/s^2 USCS (fps) Lb Slug Ft/s^2 *Work: force multiplied by the distance through which the force acts. The Newton *(N) The SI unit of force. 1 N = 0.225 lbs The Joule (J) Amount of work done by a force of one newton acting through a distance of one meter.
