What is kg to joules?

Answer 1

You cannot.

A kilogram is a measure of mass while a Joule is a measure of energy. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

Answer 2

Kilograms (kg) and joules (J) are units of different physical properties. Kilograms measure mass, while joules measure energy. You can't convert directly from kilograms to joules without a specific context or equation relating the two units, such as with the equation E=mc^2 for converting mass to energy.

Answer 3

The 'K' in 'KJ' stands for "kilo". That's the multiplier "1,000" .

So 1 KJ = 1,000 joules.

The same 'K' is also found in

-- Kilometer (distance, 1,000 meters)

-- Kph (speed, kilometer per hour)

-- Kilohertz (frequency, 1,000 hertz)

-- Kilopascal (pressure, 1,000 pascals)

-- Kilowatt (power, 1,000 watts)

-- Kilowatt-hour (energy, 1,000 watt-hours)
