Metric Units Mass Gram Volume Liter Temperature Celsius Kelvin Time Second Distance Meter Speed/Velocity m/s Acceleration m/s 2 Force Newton (N) kg  m/s 2

Energy / Work Joule (N  m) Power Watt (J/s) Momentum Kg  m/s Frequency Cycles/sec (Hz) Density g/mL Voltage (potential difference) Volts Current Amperes Resistance Ohms ( Ω ) Intensity of Light Candela (cd)

Conversion factors 1 inch = 2.54 cm 1 mile = 1.61 km 1 kg= 2.21 lbs 1 lb = 4.448 N 746 W = 1 hp (horsepower) Celsius to Kelvin = °C + 273 Celsius to Fahrenheit = (9/5 x °C) + 32 Fahrenheit to Celsius = 5/9 (°F – 32)
