ENGLISH vs. METRIC 1 inch = 2.54cm 1 foot = 0.305m 1 yard = 0.914m 1 mile = 1609m= 1.609km

About how many kilograms is a 160 pound student? 1 pound = 0.455kg A 1kg mass is equal to the mass of one liter of water. About how many kilograms is a 160 pound student?

1 quart = 0.947 liters

0.62 mph = 1 kilometer per hour
