Chapter 7 - Measurement - 7.3 The Metric System - Capacity and Weight (Mass) - 7.3 Exercises - Page 502: 77

(a) 1Tm=1,000,000,000,000m (b) 1Tm=1,000Gm 1Tm=1,000,000Mm

Since the prefix T means one trillion, 1Tm is one trillion meters. Use the unit fractions from the earlier exercises to convert Tm to Gm and Mm. $1Tm=1Tm\times\frac{1,000,000,000,000m}{1Tm}\times\frac{1Gm}{1,000,000,000m}= 1,000Gm$ $1Tm=1Tm\times\frac{1,000,000,000,000m}{1Tm}\times\frac{1Mm}{1,000,000m}= 1,000,000Mm$
