Conversions
Energy Converter
Translate any energy quantity into joules, kilojoules, calories, kilocalories, watt-hours, or kilowatt-hours at once.
Translate energy between joules, calories, and watt-hours.
Energy factors
1 cal = 4.184 J, 1 kcal = 4,184 J, 1 Wh = 3,600 J, and 1 kWh = 3.6×10⁶ J. The calculator keeps every conversion synchronized.
How to use
- Enter the known value.
- Select the unit it represents.
- Review the equivalent energy across the remaining units.
Example
Input: Value = 2 kWh
Output: Joules ≈ 7.2 MJ, Calories ≈ 1.72×10⁶ cal

Deep dive & study plan
The Energy Converter is a go-to tool whenever you need to swaps between joules, calories, and watt-hours in one view.. It focuses on energy, joule, watt-hour, which means searchers often arrive with intent-heavy queries like “how to energy converter quickly” or “energy converter formula explained.” Use this calculator to capture those intents and keep learners on the page long enough to send positive engagement signals.
Under the hood, the calculator leans on 1 cal = 4.184 j, 1 kcal = 4,184 j, 1 wh = 3,600 j, and 1 kwh = 3.6×10⁶ j. the calculator keeps every conversion synchronized.—that’s why we surface the full expression (“Energy Converter”) directly above the interactive widget. When you embed that formula inside H2s or supporting paragraphs, you help both humans and crawlers understand what entity the page represents.
Execution matters as much as the math. Follow the built-in procedure: Step 1: Enter the known value. Step 2: Select the unit it represents. Step 3: Review the equivalent energy across the remaining units.. Each numbered instruction is short enough to scan on mobile but descriptive enough to satisfy Google’s Helpful Content guidelines. Encourage students to jot down units, double-check signs, and compare answers with the Example card to build confidence.
The Example section itself is packed with semantic clues: “Value = 2 kWh” leading to “Joules ≈ 7.2 MJ, Calories ≈ 1.72×10⁶ cal.” Pepper similar narratives throughout your copy (and internal links from related guides) so canonical search intents are answered without pogo-sticking back to Google.
Quick retention checklist
- Speak the formula aloud (or annotate it) so the relationships stick.
- Write each step in your own words and compare with the numbered list above.
- Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
- Link out to at least two related calculators to keep readers exploring your topical hub.
FAQ & notes
Is there a difference between nutritional and physics calories?
Yes—nutritional calories are kilocalories. The converter lists both so you can match the context you care about.
Can I convert BTUs?
Not yet. Convert BTUs to joules manually (1 BTU ≈ 1,055.06 J) and paste the result here.
What formula does the Energy Converter use?
1 cal = 4.184 J, 1 kcal = 4,184 J, 1 Wh = 3,600 J, and 1 kWh = 3.6×10⁶ J. The calculator keeps every conversion synchronized.
How do I use the Energy Converter?
Enter the known value. Select the unit it represents. Review the equivalent energy across the remaining units.
