Question

1) how many mg are equal are in 64 hectometers?2) 52000 micrometers (um) to Gm (giga)

Answer 1

1) 64 * 10^5 mg 2) 5.2 * 10^-11gm

Explanation:

There is no direct conversion from mg to hectometers

The conversions available:

1 m³ = 10^-6 hm³

where hm = hectometer

Also 1 hm³ = 1 * 10 ^15 mg

64 hm³ = 64 * 1 * 10 ^15 mg

= 64 * 10 ^15 mg

1 hm³ = 1hm * 1hm * 1hm

To get 1 hm, we will find the cube root of the value in mg:

$\begin{gathered} 1hm\text{ = }\sqrt[3]{10^{15}mg} \\ 1\text{ hm = }10^5mg \\ 64\text{ hm = 64}\times10^{^5}mg \end{gathered}$

64 hectometers = 64 * 10^5 mg

2) 1 µm = 10^-15gm

52000 µm = 52000 * 10^-15gm

= 5.2 * 10 ^4 * 10^-15gm = 5.2 * 10^(4-15) gm

= 5.2 * 10^-11gm
