Approximate Lumen Output = Candle Power X 12.57
Footcandles X 10.764 = Lumens / Square Meter = Lux
Lumens X .07958 = Spherical Candle Power
Lux X .0929 = Foot Candles
Light Calculations
Answer
Power Calculations
Answer
Power = Voltage X Current
Watts = Volts X Amps
Current = Power / Voltage
Amps = Watts / Volts
Unit Conversions
Answer
Inches = Millimeters / 25.4
Millimeters = Inches X 25.4
Feet = Meters / .3048
Meters = Feet X .3048
Centigrade = .556 X (Fahrenheit – 32)
Fahrenheit = 1.8 X (Centigrade + 32)
Voltage Drop Calculations
Answer
Calculation: V = I x L x (R/1000) x 1.004
V = Voltage Drop
I = Current
L = Length of Conductor in Feet
R = Resistance of Conductor per 100 Feet
- R / 18awg = 6.51
- R / 16awg = 4.09
- R / 14awg = 2.58
- R / 12awg = 1.62
- R / 10awg = 1.02
- R / 8awg = 0.64
