Question

What is the number of significant digits in the number 2510000000?

Convert 8.81 lbm/(ft^3 min) to SI units

Answer 1

The significant figures of a number are digits that take meaning contributing to its measurement resolution.

The number of significant digits in the number 2510000000 is 10 .

Convert 8.81 lbm/(ft^3 min) to SI units

There are seven base units in the SI system:

• the kilogram (kg), for mass.
• the second (s), for time.
• the kelvin (K), for temperature.
• the ampere (A), for electric current.
• the mole (mol), for the amount of a substance.
• the candela (cd), for luminous intensity.
• the meter (m), for distance.

1.00 lbm= 0.453592 kg

1.00 ft^3 = 0.0283168 m^3

1.00 min = 60 Sec

Convert 8.81 lbm/(ft^3 min) to SI units means kg / (m^3 s) as follows:

8.81 *( lbm * 0.454 kg/1.00 lbm) / (ft^3*0.0283m^3/ 1.00 ft^3   * min*60 Sec/1.00 min)

3.99974/ 1.698 kg / (m^3 s)

2.36 kg / (m^3 s)
