Convert Between Units of Electric Resistance
Energy measures the capacity to do work or transfer heat. It appears in mechanical work, thermal processes, electrical usage, and chemical reactions. Common units include joules (J), kilojoules (kJ), megajoules (MJ), watt-hours (Wh), kilowatt-hours (kWh), and BTU. Converting energy units helps when comparing equipment specs, fuel content, heating and cooling loads, and utility billing.
About Electric Resistance Conversions
Helpful context and notes for converting Electric Resistance units.
A frequent confusion is energy versus power. Power is a rate (W or kW), while energy accumulates over time (Wh or kWh). For example, a 2 kW heater running for 3 hours uses 6 kWh of energy. Another common mix is between joules and watt-hours: 1 Wh equals 3600 J. Thermal work often uses BTU, while engineering calculations may use kJ or MJ. Converting energy units makes it easier to compare apples to apples across disciplines.
Practical tip: keep two anchors. 1 kWh equals 3.6 MJ, and 1 Wh equals 3600 J. If you are converting electricity use, kWh is usually the most intuitive because it matches billing. If you are converting mechanical or thermal energy, kJ and MJ often fit better. When an energy value looks unusually high or low, check whether you accidentally converted power as if it were energy, or missed the time component.

Fun Fact
One byte can store a single character, like the letter 'A'. It is the digital equivalent of saying 'hi' - tiny, but it starts the whole conversation.
