Metric pump sheets give m³/h, but US pipes and valves use GPM. Multiply by 4.4029 to match them. Quick answer: multiply the flow in m³/h by 4.4029. For example, 10 m³/h is 44.029 GPM, 50 m³/h is 220.14 GPM and 100 m³/h is 440.29 GPM. The m³/h to GPM formula A cubic metre is 1,000…
When someone says calories about food, they mean kilocalories. So the answer you want is kJ divided by 4.184, and the small calorie is 1,000 times that. Quick answer: divide the kilojoules by 4.184 to get food Calories (kcal). For example, 100 kJ is 23.9 kcal, 1,500 kJ is 358.5 kcal and 2,000 kJ is…
A 5 V supply across a 1,000 ohm resistor pushes 5 mA, a small current of the kind a status light uses. Quick answer: Divide the voltage by the resistance in ohms, then multiply by 1,000. For example, 5 V across 1,000 Ω is 5 mA, 12 V across 470 Ω is 25.532 mA and…
A 50 ohm resistor has a conductance of 0.02 siemens, which is 20 millisiemens. Quick answer: Divide 1 by the resistance in ohms. For example, 50 ohms is 0.02 S, 5 ohms is 0.2 S and 200 ohms is 0.005 S. The ohms to siemens formula Siemens equal one divided by ohms. The siemens is…
An EV took 30 kWh in 4 hours, so the charger delivered an average of 7.5 kW, which is about 33 amps at 230 V. Quick answer: Divide the kWh by the hours to get kW, then turn the kW into amps with the voltage. For example, 10 kWh over 5 h at 230 V…
Some tools report size in bytes. Divide the bytes by 1,000,000,000 to see the GB. Quick answer: multiply the size in B by 0.000000001. For example, 1,000,000,000 B is 1 GB, 5,000,000,000 B is 5 GB and 64,000,000,000 B is 64 GB. The B to GB formula One GB is 10⁹ bytes, which is 1,000,000,000…
A 30 degree API crude has a specific gravity of about 0.876, or roughly 875 kg/m3. Quick answer: Add 131.5 to the API gravity, then divide 141.5 by the result. For example, 10 API is 1 SG, 30 API is 0.8762 SG and 40 API is 0.8251 SG. The API to density formula Specific gravity…
A level of 30 dBm is exactly 1 watt, and 30 dBW is 1,000 watts. Quick answer: Divide the dB by 10, raise 10 to that power, then multiply by the reference power. For example, 30 dBm is 1 W, 0 dBm is 0.001 W and 10 dBW is 10 W. The dB to watts…
20 nickels make exactly 1 dollar. Quick answer: Multiply the number of nickels by 0.05, or divide by 20. For example, 20 nickels is 1 dollars, 40 nickels is 2 dollars and 100 nickels is 5 dollars. The nickels to dollars formula Dollars equal the number of nickels times 0.05. A nickel is worth 5…
1,000 mg of baking soda fills only about 0.2 teaspoon, while 1,000 mg of water fills about 0.2 teaspoon too. Quick answer: Divide the mg by 1,000, multiply by 48 and divide by the grams per cup. For example, 1,000 mg of baking soda is 0.2087 tsp, 1,000 mg of granulated sugar is 0.24 tsp…
