This is a tricky question. Quantum mechanicss shows us that all energy can be turned into mass and all mass into energy. To work out the equivilant mass of an amount of energy (or vice versa) simply use einsteins famous equation E= mc^2 - rearrange m = E/c^2 I do not know of any device that can directly "weigh energy".

How many kilograms of natural gas One MM BTU of natural gas weigh?
Federal Energy Regulatory Commission
How much energy do you use when swimming?
It depends on how much you weigh and what stroke you do for example if you are doing breast stroke it will use less than a butterfly stroke.
Bucket of water weighs two kiloswhat do you add to make it weigh half?
Assuming an ambient temperature of 293.15K then adding around 2608kJ of energy should do the trick nicely.
If you weigh 69 lb what will you weigh on Mars?
You would weigh about 26 pounds.
If you weigh 48.3kilograms how much do you weigh in pounds?
If your mass is 48 kg, then you weigh 105.8 pounds on earth.
What energy conversion is going on in the body as energy from food is turned into fat?
You start to weigh more.
What does a kcal weigh?
A kilocalorie is not a measure of weight. It is a measure of energy
How much does it cost to fix earthquake damage in a year?
no because energy is nothing its just energy it doesn't weigh anything
What are the benefits of LED tv's?
energy efficient weigh less than tube TVs
How many kilograms of natural gas One MM BTU of natural gas weigh?

Two identical books the weigh the same one dropped at 5 feet the other at 2 feet which has the most potential energy?
The one at 5ft has 2.5 times the energy as the one at 2ft
Do caterpillar feces weigh the same as the leaf they ate?
No. Some of the material is used up in providing energy and materials for the caterpillar to grow.
Does a wire weigh more according to relativity if electricity flows through it?
Yes. The effect is almost completely negligible but the electrons have more kinetic energy in the wire and this extra energy translates into additional mass.
How much does a 100000 light year ray of light weigh?
Light has mass since it has energy. Energy depends on the wavelength/frequency. Einstein and Planck get credit for working this out. Using red light of wavelength 650nm travelling in a vacuum we get a mass of 3.4x10^-36 kg. The weight depends on the gravity, but on Earth that would weigh roughly 3.332x10-35 N.
If energy has mass and mass has weight do we weigh more when we have lots of energy?
The idea is not that energy 'has' mass. The idea is that mass and energy can be directly related to one another in an equation. Also, mass does not always have weight; you can weigh a mass only when the mass is in a gravitational field. Having lots of 'energy' has no affect on your weight. The above stated answer is partly wrong because Einsteins E=MC2 equation qualitatively states that energy in reality does have mass. It is only that the speed of light is so great in term's of numerical value that any change in energy would not effectively affect your total mass. However weight is simply a force so you can not say that if my mass increases on earth i would have the same weight as on the moon for the same weight.
How much energy do you use when swimming?
It depends on how much you weigh and what stroke you do for example if you are doing breast stroke it will use less than a butterfly stroke.
How much does the smallest thing in the world weigh?
nothing. the smallest thing would be something smaller than a particle of an atom. Perhaps a unit of energy.
