5 g of water is about 5 mL, which is roughly 100 drops from a standard dropper. Quick answer: Turn grams into mL, then multiply by 20 drops per mL. For example, 5 g of water is 100 drops, 5 g of granulated sugar is 118.29 drops and 5 g of brown sugar (packed) is…
A label gives Btu per hour, but you want watts. Divide Btu/h by 3.4121 to switch. Quick answer: multiply the result in Btu/h by 0.29307. For example, 10,000 Btu/h is 2,930.71 W, 12,000 Btu/h is 3,516.85 W and 5,000 Btu/h is 1,465.36 W. The Btu/h to W formula One watt is about 3.412142 Btu per…
A 3 minute CD quality stereo track takes about 31.75 MB as an uncompressed file. Quick answer: Multiply sample rate, bit depth, channels and seconds, then divide by 8. For example, 44,100 Hz, 16-bit, 2 ch, 180 s is 31.752 MB, 48,000 Hz, 24-bit, 2 ch, 60 s is 17.28 MB and 44,100 Hz, 16-bit,…
40° 26′ 46″ is 40.4461 decimal degrees, because the minutes are divided by 60 and the seconds by 3,600. Quick answer: Divide the minutes by 60, divide the seconds by 3,600, and add both to the degrees. For example, 40° 26′ 46″ is 40.446 deg, 38° 53′ 23″ is 38.89 deg and 51° 30′ 26″…
Hectograms are the quiet middle rung of the metric mass ladder, sitting exactly ten to a kilogram and one hundred grams each. Quick answer: multiply the kilograms by 10. So 1 kg is 10 hg, 2.5 kg is 25 hg, 0.5 kg is 5 hg and 0.1 kg is 1 hg. The kilograms to hectograms…
US sizes use cubic feet, while the rest of the world uses mL and liters. Multiply ft³ by 28,316.85 to switch. Quick answer: multiply the volume in ft³ by 28,316.85. For example, 1 ft³ is 28,316.85 mL, 2 ft³ is 56,633.69 mL and 10 ft³ is 283,168.47 mL. The ft³ to mL formula One cubic…
Loans, leases and employment contracts are quoted in years but paid in months, and the exchange rate between the two is the friendliest number in time: twelve. Quick answer: multiply the years by 12. So 1 year is 12 months, 2.5 years is 30 months and 30 years is 360 months. For a part year,…
There is a coldest possible temperature, and the Kelvin scale starts exactly there. Convert any Celsius reading to kelvin and you are measuring how far it sits above that absolute floor, which is why physicists, chemists and engineers reach for this conversion all the time. Quick answer: add 273.15 to the Celsius temperature. So 0…
A walking adult moves at about 140 cm per second, which is 1.4 m/s. Quick answer: Divide the speed in cm/s by 100 to get m/s. For example, 10 cm/s is 0.1 m/s, 140 cm/s is 1.4 m/s and 250 cm/s is 2.5 m/s. The cm per second to m/s formula Speed in metres per…
A wheel that turns at 60 RPM has an angular velocity of 6.283 radians per second, because it makes one turn each second. Quick answer: Multiply the RPM by 2 pi and divide by 60. For example, 60 RPM is 6.283 rad/s, 600 RPM is 62.832 rad/s and 6,000 RPM is 628.32 rad/s. The RPM…
