About Kilowatt Hour (kWh)
A kilowatt-hour (kWh) is the energy consumed by a 1,000-watt (1 kW) device operating for one hour — equal to 3,600,000 joules. It is the standard unit on residential and commercial electricity bills worldwide. One kWh is a tangible, human-scale quantity: it runs a 60 W lightbulb for 16.7 hours, powers a modern refrigerator for a day, or adds about 6 km of range to a typical electric vehicle. Global electricity consumption and power plant outputs are expressed in terawatt-hours (TWh).
A typical US household uses about 886 kWh per month. Charging an electric vehicle from empty to full takes 50–100 kWh depending on battery size.
About Kilograms of TNT (kgTNT)
A kilogram of TNT (kgTNT) equals 4,184,000 joules and is used to express the energy of larger explosive charges, mining blasts, and the energy comparisons for industrial accidents or meteor impacts. One kilogram of TNT is roughly the explosive power of a typical anti-personnel mine or a small improvised explosive device. The unit bridges the gap between gram-scale charges and the ton-scale yields of large munitions.
A typical artillery shell contains 1–5 kg of explosive equivalent. The 1995 Oklahoma City bombing used about 2,000 kg of TNT equivalent in ammonium nitrate.
Kilowatt Hour – Frequently Asked Questions
What is the difference between kW and kWh?
A kilowatt (kW) is a rate of energy use — power. A kilowatt-hour (kWh) is a total amount of energy consumed over time. A 2 kW heater running for 3 hours uses 6 kWh. Your electricity meter tracks cumulative kWh, not kW. Confusing the two is one of the most common mistakes in energy discussions, similar to confusing speed with distance.
How many kWh does the average US household use per month?
The US Energy Information Administration puts the national average at about 886 kWh per month (roughly 29 kWh per day). Homes in hot states like Louisiana average over 1,100 kWh due to air conditioning; mild-climate states like Hawaii average under 500 kWh. A household's bill equals kWh consumed multiplied by the local rate, typically $0.10–$0.30 per kWh.
How many kWh does it take to fully charge an electric car?
Most EVs have battery packs of 50–100 kWh. A Tesla Model 3 Long Range holds about 75 kWh; a Rivian R1T about 135 kWh. Charging from empty to full at home costs roughly $7–$20 depending on battery size and local electricity rates. At $0.15/kWh, a 75 kWh charge costs $11.25 — far cheaper than filling a petrol tank for equivalent range.
How much does one kilowatt-hour of electricity cost?
In the US, residential electricity averages about $0.16/kWh nationally but ranges from $0.10 in Louisiana to $0.45 in Hawaii. In Europe, prices are higher: Germany averages €0.30–0.40/kWh. One kWh runs a modern fridge for about 24 hours, powers a 55-inch LED TV for 10 hours, or charges a smartphone roughly 80 times.
How many kWh does a solar panel produce per day?
A standard 400 W residential solar panel produces about 1.2–2.0 kWh per day depending on location, orientation, and weather. In sunny Arizona, expect the high end; in cloudy Seattle, the low end. A typical US home rooftop system of 20 panels (8 kW) generates roughly 25–40 kWh per day — enough to cover most or all of the household's electricity needs.
Kilograms of TNT – Frequently Asked Questions
How much destruction can one kilogram of TNT cause?
One kilogram of TNT releases 4.184 MJ — enough to shatter windows within several meters and cause serious injury at close range. In open air, 1 kg of TNT produces a blast overpressure lethal to humans within about 2–3 meters. The effect depends heavily on confinement: the same charge inside a vehicle or building is far more destructive than in open ground.
What everyday objects have the energy equivalent of one kilogram of TNT?
One kilogram of TNT (4.184 MJ) is roughly the kinetic energy of a 1,500 kg car traveling at 75 km/h, or the energy stored in about 120 mL (half a cup) of petrol. It is also the chemical energy in roughly one large meal (1,000 kcal). The difference is that TNT releases its energy in microseconds rather than hours.
How is kilograms of TNT used in mining and demolition?
Mining engineers express blast charge sizes in kg of TNT equivalent to standardize across different commercial explosives. A typical quarry blast hole uses 5–50 kg of ANFO (ammonium nitrate/fuel oil), equivalent to roughly 4–37 kg TNT. Building demolition charges range from 10 to several hundred kg TNT equivalent, carefully placed at structural weak points.
What is the TNT equivalent of common military munitions in kilograms?
A standard 155 mm artillery shell contains about 7–11 kg of TNT equivalent. A 500 lb (Mk 82) air-dropped bomb holds roughly 87 kg of TNT equivalent. An RPG-7 warhead is about 1–2 kg TNT equivalent. Anti-tank mines range from 5–10 kg TNT equivalent. These figures represent explosive fill, not total weapon weight.
How many kilograms of TNT equal one stick of dynamite?
A standard stick of commercial dynamite (about 200 g, 20 cm long) has a TNT equivalence of roughly 0.25–0.30 kg, since dynamite is about 1.25–1.5× as powerful as TNT by weight. Eight sticks of dynamite are roughly equivalent to one kilogram of TNT. Modern mining rarely uses traditional dynamite, preferring cheaper ANFO or emulsion explosives.
