Question

How to convert between measurement units?

Answer 1

Physics problems frequently ask you to convert between different units of measurement. For example, you may measure the number of feet your toy car goes in three minutes and thus be able to calculate the speed of the car in feet per minute, but that’s not a standard unit of measure, so you need to convert feet per minute to miles per hour, or meters per second.

For another example, suppose you have 180 seconds — how much is that in minutes? You know that there are 60 seconds in a minute, so 180 seconds equals three minutes. Here are some common conversions between units:

1 m = 100 cm = 1,000 mm (millimeters)

1 km (kilometer) = 1,000 m

1 kg (kilogram) = 1,000 g (grams)

1 N (newton) = 105 dynes

1 J (joule) = 107 ergs

1 P (pascal) = 10 Ba

1 A (amp) = 0.1 Bi

1 T (tesla) = 104 G (gauss)

1 C (coulomb) = 2.9979 x 109 Fr
