Solve these volume/capacity problems

1 liter = 34 US fluid ounces 2 liter soda: 2 x 34 = 68 fluid ounces

Comparing Metric and Customary Units
1 pound = .45 kg or 450 gm 1 yard = .90 m or 90 cm 1 cup = 250 ml 1 pint = 500 ml 1 quart = 1 L 1 gallon = 4 L

Time 1 minute = 60 seconds 60 minutes = 1 hour 24 hours = 1 day
365 days = 1 year

What is Light year? It is the distance light travels in one year
So how far is that? Light travels: 186,000 mi/sec 300,000 km/sec

What is Light year? In 1minute: 300,000 x 60 = 18,000,000 km
In 1 hour: 18,000,000 x 60 = 1,080,000,000 km 1.08 x 10 km In 1 day: 1,080,000,000 x 24 = 25,920,000,000 km 2.592 x 10 km In 1 year: 25,920,000,000 x 365 = 9,460,800,000,000 km 9.46 x 10 km 9 quadrillion, 460 billion, 800 trillion km 7 9 10 12
