We assume you are converting between joule and gram calorie.

You can view more details on each measurement unit: joules or gram calorie The SI derived unit for energy is the joule.

1 joule is equal to 0.23890295761862 gram calorie..

## Is Joule a SI unit?

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

## How many joules are in a kg?

More information from the unit converter The answer is 9.80665. We assume you are converting between joule and kilogram-force meter. You can view more details on each measurement unit: joule or kilogram-force meter The SI derived unit for energy is the joule. 1 joule is equal to 0.10197162129779 kilogram-force meter.

## How do you convert grams into joules?

The answer is 101.97162129779. We assume you are converting between gram-force and joule/metre. You can view more details on each measurement unit: grams or joules per meter The SI derived unit for force is the newton. 1 newton is equal to 101.97162129779 grams, or 1 joules per meter.

## How do you calculate joules?

Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

## What is joules per gram?

Joule Per Gram (J/g) is a unit in the category of Thermal heat capacity. It is also known as joules per gram, joule/gram. Joule Per Gram (J/g) has a dimension of L2T-2 where L is length, and T is time. It can be converted to the corresponding standard SI unit J/kg by multiplying its value by a factor of 1000.

## How do you convert grams into energy?

If 1 gram of mass is converted into energy, then to determine how much energy is involved in ergs, you just multiply 1 gram by the speed of light squared, in units of centimeters per second. Energy in ergs = 1 gram x ( 30,000,000,000.0 cm/sec) x (30,000,000,000.0 cm/sec).

## Is joules in kg or g?

One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

## How do we calculate energy?

The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

## How much energy is in a gram?

Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~9×1013 joules.

## Why is there a 1/2 in the kinetic energy formula?

The short answer: Because it’s the result of integrating momentum: p = mv with respect to v. … Since this line forms the hypotenuse of a triangle, the area (and thus kinetic energy) is 1/2 * base * height, where the base is the velocity, and the height is momentum, or mv. Hence K = 1/2(v)(mv) = 1/2mv^2.

## What do you mean by 1 Joule?

One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second.

## What is the efficiency formula?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

## What is the kinetic energy of an object?

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. … Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive.

## What is the specific heat of water?

For example, at a temperature of 25 °C (the specific heat capacity can vary with the temperature), the heat required to raise the temperature of 1 kg of water by 1 K (equivalent to 1 °C) is 4179. 6 joules, meaning that the specific heat of water is 4179. 6 J·kg−1·K−1.

## What is the kinetic energy formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is E mc2 used for?

Einstein’s equation E = mc2 shows that energy and mass are interchangeable. The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light.

## What is measured in ergs?

Erg, unit of energy or work in the centimetre-gram-second system of physical units used in physics; to lift a pound weight one foot requires 1.356 × 107 ergs. … It equals the work done by a force of one dyne acting through a distance of one centimetre and is equal to 10-7 joule, the standard unit of work or energy.
