With great difficulty. The easy bit was shillings: there were 20 shillings in a pound and 100 decimal pennies. At the time of their introduction, the latter were called New Pence (NP) and I will stick to that notation.So 1 shilling = 0.05 pounds = 5 NP.


The problem came with converting 12 [old] pennies in a shilling to 5 NP. A saving grace was that there was still a 1/2 New Penny coin

Formally, that was done though rounding:

1p = 0.41666... NP

2p = 0.83333... NP

3p = 0.1.25 NP

4p = 0.16666... NP

5p = 2.08333... NP

6p = 2.5 NP

7p = 2.91666... NP

8p = 3.33333... NP

9p = 3.75 NP

10p = 4.1666... NP

11p = 4.5833... NP

12p = 5.0 NP


Conversion tables were published but I am sure that many people were ripped off before the transition settled down.

How do you do British pre-decimal math?

All school kids got used to it very quickly. The maths of predecimal currencies was another reason for the conversion to a decimal based currency system. There were 12 Pennies in a Shilling, and 20 Shilling in a Pound. That is what you need to remember. Add these two predecimal values - £3/15/6 - 3 Pounds, 15 Shillings and 6 Pence. £2/ 7/ 8 - 2 Pounds, 7 Shillings and 8 Pence. Add the pennies first. 8 Pence + 6 Pence = 14 Pence. 14 Pence = 1 Shilling and 2 Pence. Put down the 2 Pence and carry the 1 Shilling. £ / / 2 Next, add the Shillings starting with the carried over 1 Shilling from the Pence addition. 1 Shilling + 7 Shillings + 15 Shillings = 23 Shillings. 23 Shillings = 1 Pound and 3 Shillings. Put down the 3 Shillings and carry the 1 Pound. £ / 3/ 2 Finally, add the Pounds starting with the carried over 1 Pound from the Shillings addition. 1 Pound + 2 Pound + 3 Pound = 6 Pounds. £6/ 3/ 2 - Total = 6 Pounds, 3 Shillings and 2 Pence. Easy. This was mental arithmetic for shopkeepers and other business people in predecimal days.


What is 5 and 6 pence worth in American money?

The expression "5 and 6 pence" means "5 shillings and 6 pence", and refers to the monetary system used in Great Britain prior to decimalization in 1968. Under the "£sd" system (which stands for Pounds-Shillings-Pence), there were 12 pence to a shilling and 20 shillings to a pound. Thus "5 and 6 pence" would mean 5.5 shillings or 5.5/20ths of a pound - 27.5p in today's decimal terms. While shillings and the old style pence no longer circulate, 27.5p would be about 40 US cents as of mid-January 2010. The exchange rate has changed over time, however, and if you are asking as it relates to a historical period (where the exchange rate, currently about GBP1.00=US$1.60, may have been markedly different), you should probably look into the exchange rate at that time, as well as inflation or cost of living since that time, to get an equivalent real value.
