About Grams of TNT (gTNT)
The gram of TNT (gTNT) is a unit of explosive energy equal to exactly 4,184 joules — the energy released by detonating one gram of trinitrotoluene. By convention, this is a defined unit; real TNT yields vary by about ±2% depending on formulation. It is used to characterize small explosive charges, improvised explosive devices, and the energy of chemical reactions involving explosives. One gram of TNT releases roughly the same energy as one dietary kilocalorie (thermochemical).
A standard firecracker releases energy equivalent to about 0.5–1 g of TNT. A hand grenade contains the explosive equivalent of roughly 60–90 g of TNT.
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.
Grams of TNT – Frequently Asked Questions
How much energy does one gram of TNT actually release?
By convention, exactly 4,184 joules — the same as one thermochemical kilocalorie. Real TNT detonation yields vary by about ±2% depending on purity and confinement, but the defined value provides a fixed reference point. This makes the gram of TNT a convenient bridge between chemistry (calories) and explosive engineering.
Why is TNT used as the standard reference for explosive energy?
TNT (trinitrotoluene) became the reference explosive because it is chemically stable, safe to handle, and was massively produced during both World Wars. Its consistent detonation properties made it a natural benchmark. Other explosives are rated by their "TNT equivalent" — for example, C-4 is about 1.34× TNT and ANFO is about 0.74× TNT.
How many grams of TNT equivalent does a firecracker contain?
A standard US consumer firecracker contains about 0.5–1 gram of TNT equivalent in flash powder. An M-80 (now illegal for consumer sale) contained roughly 3 g of TNT equivalent. Cherry bombs were about 1.5 g. Commercially sold fireworks are regulated by the CPSC to contain no more than 50 mg of flash powder per report charge.
What is the TNT equivalent of a hand grenade?
A US M67 fragmentation grenade contains about 180 g of Composition B explosive, which has a TNT equivalence of about 1.33×, giving roughly 240 grams of TNT equivalent. The lethal radius is about 5 meters, with a casualty-producing radius of 15 meters. The fragmentation — not the blast energy alone — is the primary wounding mechanism.
How does the gram of TNT relate to the calorie?
One gram of TNT releases exactly 1 thermochemical kilocalorie (1 kcal = 4,184 J) by definition. This means a dietary Calorie (nutritional kcal) contains the same energy as detonating one gram of TNT. A 2,000-Calorie daily diet is energetically equivalent to 2 kg of TNT — though your body releases that energy over 24 hours, not in microseconds.
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.
