## Converting pounds to ounces

1, start text, space, p, o, u, n, d, end text, equals, start color #28ae7b, 16, end color #28ae7b, start text, space, o, u, n, c, e, s, end text
To convert pounds to ounces we multiply the number of pounds by start color #1fab54, 16, end color #1fab54.
Example:
start color #ff00af, 30, end color #ff00af, start text, space, p, o, u, n, d, s, end text, equals, start color #ff00af, 30, end color #ff00af, times, start color #28ae7b, 16, end color #28ae7b, equals, start color #6495ed, 480, end color #6495ed, start text, space, o, u, n, c, e, s, end text

## Converting ounces to pounds

1, start text, space, o, u, n, c, e, end text, equals, start fraction, 1, divided by, start color #28ae7b, 16, end color #28ae7b, end fraction, start text, space, p, o, u, n, d, end text
To convert ounces to pounds we divide the number of ounces by start color #1fab54, 16, end color #1fab54.
Example:
start color #ff00af, 112, end color #ff00af, start text, space, o, u, n, c, e, s, end text, equals, start fraction, start color #ff00af, 112, end color #ff00af, divided by, start color #28ae7b, 16, end color #28ae7b, end fraction, equals, start color #ff00af, 112, end color #ff00af, divided by, start color #28ae7b, 16, end color #28ae7b, equals, start color #6495ed, 7, end color #6495ed, start text, space, p, o, u, n, d, s, end text

• how does 8tons = 16000
• bc 8 times 2 is 16 and then you just add the 3 zeros.
• how do I know if I need to multiply or dived?
• To convert "bigger" units to "smaller" ones, you multiply.
To convert "smaller" to bigger, you divide.
Pound is something big, and ounce is something small - smaller parts make one big thing - 16 ounces are in a pound.
To convert pounds to ounces, you multiply by 16.
To convert ounces to pounds, you divide by 16.
