Problems - Conversion Tables

Question 1:
Using conversion factors, determine the number of
a. Btu in 5 J of energy.
b. cubic meters in 24 oz of a liquid.
c. seconds in 1.4 days.
d. pints in 1 m^3 of a liquid.

Solution 1:
a. 5 J
= 5 J x (0.000948 Btu / 1 J)
= 4.74 x 10^-3 Btu

b. 24 oz
= 24 oz x (1 m^3/ 1000 L) x (3.785 L/ 128 oz)
= 7.1 x 10^-4 m^3
c. 1.4 days
 = 1.4 days x (24 h / 1 day) x (3600 s / 1 h)
= 1.21 x 10^5 s
d. 1 m^3
= 1 m^3 x (1000 L/1 m^3) x (2 pints/0.9463L)
= 2113.49 pints
