386 km/s = ________ m/ms ?

1270 g/L = _______ g/mL ?

1270 g/L = ________ kg/mL ?

615 mK/s = _______ K/s ?

615 mK/s = ________ μK/ms?

2.999 mg/mL = _______ g/L ?

2.999 mg/mL = ________ μg/mL?

Answer 1

1. 386 km/s = _______ cm/s ?

1 km/s = 100000 cm/s [1 km = 100000 cm]

Then 386 km/s = 386 *100000 cm/s

386 km/s = 38600000 cm/s

1. 386 km/s = ________ m/ms ?

1 km/s = 1 m/ms [1 km = 1000 m and 1s = 1000 ms so 1 km/s = 1000m/1000ms]

Then 386 km/s = 386 m/ms

1. 1270 g/L = _______ g/mL ?

1 g/L = 0.001 g/ml [ 1 L = 1000 mL so 1 g/L = 1g/1000 mL]

Then 1270 g/L = 1270 * 0.001 g/ml

1270 g/L = 1.27 g/mL

1. 1270 g/L = ________ kg/mL ?

1 g/L = 10^-6 kg/mL [1 g = 10^-3 kg and 1L = 10³ ml so 1 g/L = 10^-3 kg/10³ mL

Then 1270 g/L = 1270 * 10^-6 kg/mL

1270 g/L = 1270 * 10^-6 kg/mL

1270 g/L = 0.001270 kg/mL

1. 615 mK/s = _______ K/s ?

1 mK/s = 10^-3 K/s [1 m = 10^-3 so 1 mK = 10^-3 K

Then 615 mK/s = 615 * 10^-3 K/s

615 mK/s = 0.615 K/s

1. 615 mK/s = ________ μK/ms?

1 mK/s = 1 μK/ms [1 m = 10³μ and 1s = 10³ ms so 1 mK/s = 10³μK/10³ ms

Then 615 mK/s = 615 μK/ms

1. 2.999 mg/mL = _______ g/L ?

1 mg/mL = 1 g/L then 2.999 mg/mL = 2.999 g/L

1. 2.999 mg/mL = ________ μg/mL?

1 mg/mL = 1000 μg/mL then 2.999 mg/mL = 2.999*1000 μg/mL

2.999 mg/mL = 2999 μg/mL
