Length worksheet

1. In ångströms: 1,778,000,000 Å

1. Change to meters first, because every unit is measured against the meter. 1 in = 0.0254 m, so multiply

   $7\text{\hspace{0.17em}in}\times 0.0254$$=0.1778\text{\hspace{0.17em}m}$

2. Now change the meters into ångströms. 1 Å = 0.0000000001 m, so divide

   $\frac{0.1778\text{\hspace{0.17em}m}}{0.0000000001}$$=\mathrm{1,777,999,999.9999998}\text{\hspace{0.17em}Å}$

2. In feet: 19,685.04 ft

1. Change to meters first, because every unit is measured against the meter. 1 km = 1,000 m, so multiply

   $6\text{\hspace{0.17em}km}\times \mathrm{1,000}$$=\mathrm{6,000}\text{\hspace{0.17em}m}$

2. Now change the meters into feet. 1 ft = 0.3048 m, so divide

   $\frac{\mathrm{6,000}\text{\hspace{0.17em}m}}{0.3048}$$=\mathrm{19,685.0393700787}\text{\hspace{0.17em}ft}$

3. In decimeters: 4e-8 dm

1. Change to meters first, because every unit is measured against the meter. 1 nm = 0.000000001 m, so multiply

   $4\text{\hspace{0.17em}nm}\times 0.000000001$$=0.000000004\text{\hspace{0.17em}m}$

2. Now change the meters into decimeters. 1 dm = 0.1 m, so divide

   $\frac{0.000000004\text{\hspace{0.17em}m}}{0.1}$$=0.00000004\text{\hspace{0.17em}dm}$

4. In feet: 0.98 ft

1. Change to meters first, because every unit is measured against the meter. 1 dm = 0.1 m, so multiply

   $3\text{\hspace{0.17em}dm}\times 0.1$$=0.3\text{\hspace{0.17em}m}$

2. Now change the meters into feet. 1 ft = 0.3048 m, so divide

   $\frac{0.3\text{\hspace{0.17em}m}}{0.3048}$$=0.9842519685\text{\hspace{0.17em}ft}$

5. In yards: 4,374.45 yd

1. Change to meters first, because every unit is measured against the meter. 1 km = 1,000 m, so multiply

   $4\text{\hspace{0.17em}km}\times \mathrm{1,000}$$=\mathrm{4,000}\text{\hspace{0.17em}m}$

2. Now change the meters into yards. 1 yd = 0.9144 m, so divide

   $\frac{\mathrm{4,000}\text{\hspace{0.17em}m}}{0.9144}$$=\mathrm{4,374.4531933508}\text{\hspace{0.17em}yd}$

6. In micrometers: 1,828,800 µm

1. Change to meters first, because every unit is measured against the meter. 1 ft = 0.3048 m, so multiply

   $6\text{\hspace{0.17em}ft}\times 0.3048$$=1.8288\text{\hspace{0.17em}m}$

2. Now change the meters into micrometers. 1 µm = 0.000001 m, so divide

   $\frac{1.8288\text{\hspace{0.17em}m}}{0.000001}$$=\mathrm{1,828,800.0000000002}\text{\hspace{0.17em}µm}$

7. In feet: 0.01 ft

1. Change to meters first, because every unit is measured against the meter. 1 mm = 0.001 m, so multiply

   $4\text{\hspace{0.17em}mm}\times 0.001$$=0.004\text{\hspace{0.17em}m}$

2. Now change the meters into feet. 1 ft = 0.3048 m, so divide

   $\frac{0.004\text{\hspace{0.17em}m}}{0.3048}$$=0.0131233596\text{\hspace{0.17em}ft}$

8. In feet: 1.31e-8 ft

1. Change to meters first, because every unit is measured against the meter. 1 nm = 0.000000001 m, so multiply

   $4\text{\hspace{0.17em}nm}\times 0.000000001$$=0.000000004\text{\hspace{0.17em}m}$

2. Now change the meters into feet. 1 ft = 0.3048 m, so divide

   $\frac{0.000000004\text{\hspace{0.17em}m}}{0.3048}$$=0.0000000131\text{\hspace{0.17em}ft}$

9. In miles: 9.47e-5 mi

1. Change to meters first, because every unit is measured against the meter. 1 in = 0.0254 m, so multiply

   $6\text{\hspace{0.17em}in}\times 0.0254$$=0.1524\text{\hspace{0.17em}m}$

2. Now change the meters into miles. 1 mi = 1,609.344 m, so divide

   $\frac{0.1524\text{\hspace{0.17em}m}}{\mathrm{1,609.344}}$$=0.000094697\text{\hspace{0.17em}mi}$

10. In inches: 0.28 in

1. Change to meters first, because every unit is measured against the meter. 1 mm = 0.001 m, so multiply

   $7\text{\hspace{0.17em}mm}\times 0.001$$=0.007\text{\hspace{0.17em}m}$

2. Now change the meters into inches. 1 in = 0.0254 m, so divide

   $\frac{0.007\text{\hspace{0.17em}m}}{0.0254}$$=0.2755905512\text{\hspace{0.17em}in}$
