A speed of 10 m/s sounds slow, but it equals 36 km/h, which is a strong cycling pace. Quick answer: Multiply the speed in m/s by 3.6 to get km/h. For example, 10 m/s is 36 km/h, 20 m/s is 72 km/h and 25 m/s is 90 km/h. The m/s to km/h formula Speed in…
A shaft turning at 1,000 RPM moves at about 104.7 radians per second. Quick answer: Multiply the RPM by 0.10472, which is 2 pi divided by 60. For example, 1,000 RPM is 104.72 rad/s, 10,000 RPM is 1,047.2 rad/s and 100,000 RPM is 10,471.98 rad/s. The RPM to rad/s formula Angular speed in rad/s equals…
The label says 8.50 a kilogram, the sign next door says 3.99 a pound, and one division settles which is cheaper. Quick answer: divide the price per kilogram by 2.20462. So 10.00 per kg is 4.54 per lb, and 8.50 per kg is 3.86 per lb. The price per kilogram to price per pound formula…
A rate of 5 cents per minute is 3 dollars per hour. Quick answer: Multiply the cents per minute by 60, then divide by 100. For example, 5 cents per minute is 3 dollars per hour, 10 cents per minute is 6 dollars per hour and 25 cents per minute is 15 dollars per hour….
Flow alone has no pressure. But a pump with a known horsepower and flow can only make so many psi. Quick answer: Multiply the horsepower by 1,714, then divide by the flow in gpm. The answer is the pressure in psi. For example, 10 gpm, 5 hp is 857 psi, 5 gpm, 3 hp is…
In water, 1 mg/L is 1,000 ppb. For other liquids, the density changes the answer. Quick answer: Multiply the mg/L by 1,000 and divide by the density of the liquid in g/mL. For example, 0.5 mg/L of Water is 500 ppb, 0.5 mg/L of Whole milk is 485.44 ppb and 0.5 mg/L of Olive oil…
50 µg/mL is 5 mg/dL, because 1 µg/mL equals 0.1 mg/dL. Quick answer: Multiply the µg/mL by 0.1, or divide by 10. For example, 50 µg/mL is 5 mg/dL, 100 µg/mL is 10 mg/dL and 25 µg/mL is 2.5 mg/dL. The µg/mL to mg/dL formula Milligrams per dL equal micrograms per mL times 0.1. The…
In water, 25 mg/L is 25 ppm, but in a heavier liquid the same mg/L means fewer ppm. Quick answer: Divide the mg/L by the density of the liquid in g/mL. For example, 25 mg/L at 1 g/mL is 25 ppm, 100 mg/L at 1.2 g/mL is 83.333 ppm and 500 mg/L at 0.8 g/mL…
A label that says 50 mg/g means the product is 5 percent by weight. Quick answer: Divide the mg/g value by 10. For example, 10 mg/g is 1 percent, 50 mg/g is 5 percent and 250 mg/g is 25 percent. The mg/g to percent formula Percent by weight equals the mg/g value divided by 10….
