Technical Guide & Calculation Methodologies
Appliance Power & Electricity Units (kWh) Formula
Energy Consumed (Units) = (Power in Watts × Total Quantity × Daily Hours × Days in Month) ÷ 1,000. For example, a 1500W AC running 8 hours/day for 30 days uses (1500 × 1 × 8 × 30) / 1000 = 360 kWh Units.
Scientific Calculator Angle Modes (Deg vs Rad)
In Degree Mode (DEG), full circle is 360° (e.g. sin(90°) = 1). In Radian Mode (RAD), full circle is 2π radians (e.g. sin(π/2) = 1). Use the toggle to ensure accurate engineering and physics answers.
