Going Metric (Part Two)
By Skip Williams

Thrown and Projectile Weapon Ranges

You can convert ranges for weapons using exactly the same method used for speeds. The table below shows metric ranges for the thrown and projectile weapons included in the Player's Handbook:

Spell Ranges

Spell ranges can be converted in the same manner as speeds and weapon ranges. Common ranges are shown in the table below. 

Range English Metric Squares
Personal Caster Caster --
Touch Subject touched Subject touched --
Close 25 ft. + 5 ft./caster level 10 m + 2 m/caster level 5 + 1/caster level
Medium 100 ft. + 10 ft./caster level 40 m + 4 m/caster level 20 + 2/caster level
Long 400 ft. + 40 ft./caster level 160 m + 16 m/caster level 80 + 8/caster level
0 feet Subject touched[1] Subject touched[1] --
10 feet 10 feet 2 m 2
10 feet/level 10 feet/caster level 4 m/caster level 2/caster level
15 feet 5 feet 2 m 1
20 feet 20 feet 8 m 4
30 feet 30 feet 12 m 6
40 feet/level 40 feet/caster level 16 m/caster level 8/caster level
50 feet 50 feet 20 m 10
60 feet 60 feet 24 m 12
120 feet 120 feet 48 m 24
1 mile/level 1 mile/caster level 2.1 kilometers/caster level[2] 1,056[3]
5 miles 5 miles 10.5 kilometers[2] 5,280
Other ranges in feet see note 4
1. Spells with a range of 0 feet generally involve placing some kind of sigil, glyph, or sign on something else. Such spells effectively have a range of touch but you cannot "hold the charge" as you can with a touch spell.
2. Range rounded down to the nearest 10th kilometer.
3. The exact number of squares these spells can reach seldom proves significant.
4. When a spell has a range in feet that is not listed here, simply divide the range in feet by 5 to get the number of squares it reaches. To determine the range in meters, multiply the range in squares by 2.

Spell Areas

Basic spell areas convert as shown in the table below.

*When a spell has an area measured in feet that is not listed here, simply divide the area's dimensions in feet by 5 to get the dimension in squares. To determine the dimension in meters, multiply the dimension in squares by 2.
